A flashback shows a younger Rusty in the ANO mansion hitting on Jill. Rusty reveals that he is part of the Burgmeister family, and Jill reveals that she is part of the Royce family. Tybalt does not accept Rusty to the ANO fraternity. On the way out he encounters Tommy smoking, and Tommy convinces him to start a new fraternity, as Heather rolls into college in a wheelchair. Rusty tries to convince a younger Sage to get the HOTs to party with their new DIK fraternity instead of with the jocks but fails. Nick and Vinny come to pledge for the newly formed DIKs and together they form the traditions that are now part of hell week.

Back at the present, the devil’s pledge board is being evaluated as it is revealed that some of the tasks were meant to be impossible and that the goal was not to complete the board but to see how the maggot brothers go through it. Photo evidence of the maggots completing their tasks is presented and it is revealed that Derek had sex with Wendy in the bushes after crashing the feminist protest. Jacob calls the DIK secret code to hide the evidence of the maggots having had sex with a teacher as it is revealed that every DIK has a single opportunity to use the secret code to force all other DIKs to completely forget an event, meaning that they are never allowed to talk about it having happened with anybody.

The evaluation ends successfully although the maggots forgot to egg the preps, but the HOT girls that were supposed to come to the hell week party are nowhere to be found. In the Tri-Alpha house, Arieth is hitting on Caleb as it is revealed that she also had sex with Anthony. Arieth answers the phone and tells Tommy that she’s at a hell week party in the Tri-Alpha house, and the DIKs get ready to assault the jocks. They break the Tri-Alpha house windows but it turns out that the HOTs aren’t there and only Arieth is. The jocks are reluctant to start a fight with the DIKs because of their trouble with the counselors but Caleb threatens the DIKs, saying he can fight them since he’s not yet an official jock. Humiliated, the DIKs continue searching for the HOTs and suspect they are at the ANO mansion.

At Isabella’s house, Jill and Bella comfort Cathy after the photo leak incident. Derek uses his roommate Bert’s quad-copter to spy on the ANO mansion and it is revealed that the HOTs have agreed to entertain the guests of the ANO’s Dante Week celebration, who are mostly rich B&R graduates in fancy suits. Quinn wants to make a “business proposal” to Tybalt who sends her to talk with Rich instead as Derek and the protagonist steal suits from the mansion and slip into the party undercover. There, they meet the HOT girls dissatisfied with having to provide entertainment at such a boring party. Riona reveals that Quinn made this arrangement with the ANO because they were short on money. Josy hears that her father is coming and asks the protagonist to be with her because she didn’t leave home on good terms after the fight with him and Monica and is scared of what might happen. The protagonist takes a picture of his dick on Tybalt’s phone. Ashley is crying and being comforted by Elena. Mona storms out of one of the rooms saying she can’t do it as Stephen also exits the room. Jade is with Tybalt when Stephen comes around and is unhappily surprised to see Jade at the party, saying she was supposed to meet with Cathy, to which Jade replies that Cathy canceled on her choosing to be with Bella instead. Derek is entertaining some ANO graduates as one of them is visibly drunk and lets them know that he’s looking for his daughter who should be at the party.

The protagonist calls Quinn but she is busy selling drugs to ANO vice-president Rich, who wants to buy cocaine but is convinced by Quinn, who doesn’t sell cocaine, to buy some hash instead. Sage comes around and reveals that while it’s true that the HOTs struck a deal with the ANO because they needed money, Quinn hasn’t done her part of updating Tommy and Rusty that the HOTs won’t be at the DIKs’ hell week celebration. Sage tells the protagonist that Tommy and Rusty are running the fraternity by relying on money from Rusty’s rich family, but that is not how fraternities and sororities should be run. Sage also reveals that her dad is attending this party but she doesn’t want to meet him, and they joke about parents at parties. The protagonist tells Sage about his deceased mother and she’s angry that he didn’t tell her earlier because now she feels bad having joked about mothers with him. Sage asks the protagonist to fuck her on Tybalt’s bed so hard that it breaks. While the bed is rocking a drawer opens and it is seen that he has a watermelon with Jill’s photo and underwear which he uses to masturbate.

Josy’s dad has arrived and the protagonist and Maya go looking for them. Despite Josy getting ready to fight with her dad, the meeting with him goes surprisingly well as it turns out he is supportive of her going to B&R and becomes emotional about having wanted to see his daughter on her first day at college. They make up as he brings Josy the rest of her belongings and lets her know that he transferred the payments for her tuition. Back at the party, Maya is sad that her father is nowhere near as supportive as Josy’s father.

Derek hears about the deal between the HOT and the ANO and plots to get the girls out by activating the sprinkler system and thus end the party early. Everybody runs out and the preps are horrified at the damage done to their suits by the sprinklers. Outside, Tybalt confronts the protagonist, mocks him, and slaps him. Derek and the protagonist throw eggs at the preps thus finishing their pledge board.

While walking back to their house the DIKs don’t understand why Quinn went behind their backs like this instead of just asking the DIKs to pay the HOTs for attending the party. They conclude that something else is going on but as they arrive back at the mansion, they find it destroyed with signs of the Tri-Alphas having been there while the DIKs were out. They don’t know what to do as they don’t have insurance and they don’t want to call the police because of what they’ve done to the ANO mansion.

The protagonist goes to Bella’s house to talk with Cathy. He tells the DIKs’ side of the story and manages to make her feel much better after assuring her that nobody is making fun of her and everyone is just scared of the repercussions. The protagonist drives Cathy home and advises her to stop using dating apps. Cathy is surprised that he knew it was her on the app and they have sex in Bella’s car. Back at Bella’s house, Jill and Bella praise the protagonist for helping Cathy. Bella reveals to the protagonist that Jill is of the Royce family, to the dismay of Jill who says it was a secret. Bella tries to understand why was it supposed to be a secret as the discussion gets tense and Jill accuses Bella of also hiding a secret from her about the protagonist sleeping in her home. They apologize for blaming each other as Tybalt calls and tells Jill that there was a fire at the ANO mansion and that he had a confrontation with the protagonist. Bella tells a story about her doing hell week when she was in college and falsely confessing to her teacher that she had a crush on him. The protagonist plays Bella’s favorite song on his guitar. When Bella says it’s her favorite song and he says that he remembered that, Bella and Jill exchange glances as Jill looks worried.

In Quinn’s room, Tommy is furious as Quinn reveals that the ANO party deal was not meant to raise money for the sorority, but rather to increase the profits of her drug sale operation because sales have been low lately. However, the plan failed and she barely made enough money to cover this month. She also tells Tommy that the jocks stopped buying from her, revealing that Dawe used to buy birth control pills from her which he used as steroids, and that she has been faking them and has been selling him sugar pills lately to cut costs. Tommy tells her that the DIK mansion was destroyed that night because of her and she is shocked to hear that. Tommy also tells her that he feels betrayed as Quinn’s expression shows regret or uneasiness with the situation.

As the protagonist gets ready to sleep at Bella’s house, Quinn texts him and congratulates him for passing Hell Week. The protagonist calls Sage and wakes her up, and she hangs up and goes back to sleep, and calls Maya and Josy as they discuss him becoming a DIK and staying with Isabella.

Bella and Jill are in bed. Bella is uncomfortable and an annoyed Jill assures her that it won’t happen again as they talk about an understanding they had. Bella asks her to stop talking about it as Jill snaps and goes to sleep on the couch with the protagonist. Bella drops the photo that was on her nightstand to the floor, a photo of her and James on their wedding day.

The next day, it is revealed that the protagonist’s birthday is nearing, as Neil texts him asking what he wants for a present, and also reveals that they got some letter in the mail that is related to Lynette. Sage is angry that the protagonist called her and woke her up last night. The protagonist asks Jill about the wedding photo and the mysterious locked door, and Jill refuses to give him any information, saying that he should respect Bella’s privacy. They do yoga together and Bella asks Jill about her tennis date with the protagonist, mentioning that if they talked about it earlier they could have avoided the argument yesterday. The protagonist does some more yoga with Jill and then joins Bella in the sauna. After taking a shower, Bella teaches the protagonist how to make pancakes and Jill posts a photo of them cooking on social media. Jill checks out the locked door and is also puzzled about it.

At the HOT house, Heather and Riona are complaining about the ANO party and Riona blames Sage for arranging that, as Heather blames Sage for taking too many daughters. Quinn talks to someone on the phone saying that she has everything now, and they agree to meet tomorrow night. Camila tells Quinn that Mona wants out of the “free tuition” arrangement. Sage and the protagonist practice guitar at the HOT house porch and discuss the events of last night. Sage tells him that the HOTs need to earn enough money to fund the sorority and that’s why they sometimes have to take deals such as entertaining at the ANO party, and that all fraternities also work to obtain their funds with the DIKs being the only exception. They kiss as Sarah and Melanie watch them from the window and talk about how this relationship will make it easier for Sage when Chad breaks up with her. Sarah and Melanie promise to have each other’s back if things go wrong and Melanie goes to call Chad.

At the DIK mansion, the DIKs are in shambles over how much damage has been done to their mansion and try to convince Rusty to get more money from his dad, as Rusty reveals that he has been using the funds his dad told him to save on the deal with The Pink Rose. The protagonist, now a DIK among equals, motivates them and tells them they shouldn’t rely on Rusty’s dad and should instead work together to obtain money and fix the damage. They plan to look for jobs in the community center and have Neil supply them with materials from his construction site to fix the house. Everyone agrees with the plan and applauds the protagonist for his speech except for Tommy who is pissed and goes to his room. Derek and the protagonist get their DIK jackets.
