After her boyfriend Jakov and her friend Lovro declined to attend a party, Eva goes alone. At the party, she confronts her former friend Sara. After a failed attempt to reconcile her friendship with Sara, Eva meets Nora, Tina and Nika.

Eva and Jakov spend the weekend at a vacation house, but Eva is unhappy that Jakov invited Lovro to join them.

Eva gets close with Nora, Tina and Nika as she invites them to a party at her house. A new girl, Vanessa, joins the squad.

The girls go to Nikola's birthday party in order to attempt to get close to the popular boys at the school. Vanessa tells Eva to break up with Jakov and hook up with Nikola, given that Nikola seem to be interested in her.

While attending the opening of a new bar in the city, Nora, Eva, Nika, and Vanessa discover that Roko helped Tina land a job as the bar’s hostess. Nora confronts Roko, arguing that the job is demeaning, but Roko remains insistent on pursuing a date with her. While the girls are hanging out at Nora's house, Tina wants to leave for Roko's party. Nora texts Roko asking him to stop contacting Tina, hinting she might agree to a date with him in return.

Nora confronts Roko about the bottle smashing from the party. He justifies his actions, saying that he would go to any lengths to protect those he cares about. Nora asks for space, needing time to process his unexpected violent nature. At school, Nora and Vanessa discuss the fight. Vanessa discloses she figured out Nora and Roko by herself; she defends Roko by pointing out the party crashers' racism, and questions why Nora and Roko's differences are an issue. Eva reveals the fight was about molly. By Vanessa's encouragement, Nora finally talks to Tina about Roko. To Nora's surprise, Tina reveals she has known about them since their first kiss and asks Nora if she is in love with Roko. Nora professes she is; Tina gives them her blessing.

Although Nora had planned to skip Roko’s party, she decides to go after Eva tells her that Tina embarrassed herself by flirting with Roko and left in tears after being rejected. When the police shut down the party and someone mistakenly takes Nora’s jacket—with her phone and keys inside—she is stuck at Roko’s house. Nora contacts Vito through Roko’s Instagram, then spends time with Roko playing his synthesizer. That night, Roko offers Nora his bed and sleeps on the couch, but after beer is found spilled on it, Nora invites him to share the bed.

While preparing clothes to donate to an orphanage, Eva and Nora receive an invite to a party organized by Roko’s friend group. Nora is reluctant to go because the entrance fee is meant to fund a microscope that Nikola allegedly broke. To convince her, Roko persuades Nikola to donate part of the money to orphans. At the party, Nora hides her feelings for Roko, while Eva gets drunk, kisses Tina in front of Nikola, and causes a scene. After an argument, Nora and Roko end up kissing.

Eva is inspired to revive her dating life, and Nora tells her about her date, but doesn't reveal it is with Roko. Tina wonders if Nora is a lesbian because of her perceived misandry and feminism. Eva has cold feet about her date, and Nora lies to Tina that she can't go with Eva because she has to tutor a younger student. Vito figures out that she has a date; Roko picks her up but the atmosphere between the two is cold. Nora blames him for manipulating and taking advantage of Tina; Roko retorts that he only apologized to Tina because Nora asked him to, and not to give Tina hope that they will reconcile, and also that he found a hosting job for her purely because she needed a job. Nora refuses Roko's ride home and arrives to her place where she finds the drunken Vito, Tina and Eva, whose date fell through. Tina notices that Nora wore perfume to her tutoring class, which Vito points out was held at Friday night.

Nora wakes up next to Roko, who says he waited for her, and later learns from friends that she got drunk at Sven's party and was taken home in a taxi. At Sljeme, Sven shows her disturbing photos from that night and refuses to delete them, prompting Nora to flee into the forest and have a panic attack. After spiraling and seeking medical help, both her doctor and friend Eva suspect she was drugged with GHB and urge her to speak to Roko, assuring her it wasn’t her fault.

Petra calls Nora in panic-Roko beat up Sven and both got arrested. Roko tells Nora to stay away, then ignores her. Tina encourages Nora to fight for Roko; she then attempts to stop Roko from leaving for Amsterdam.

Nora and Roko follow each other on Instagram, while she and Eva ask Vito to find out if Nikola is gay—he agrees. With Eva’s help, Nora and Roko keep their situationship secret from Tina. Nora tries, and fails, to tell Tina the truth before and during the seniors' coupe pre-party, where a fight erupts between Roko, Nikola, Lovro, their friends, and party crashers. Roko hits one of them with a glass bottle.

Nora confronts Sven about the photos and records their conversation. Sven posts one of Nora's photos online, leading Roko to believe she cheated. He decides to leave Zagreb, and despite Nora's plea, he drives away after learning the truth.
