The 18 year old Elias and 17 year old Lieve are friends, but not a couple, and move together to
Amsterdam for their studies. During introduction week they encounter former student Bram, who invites them to a party for the students of the H.S.C. Mercurius fraternity taking place that evening. Lieve asks Bram if he will join the party, who refuses at first as he hasn't been a student for years at this point, but changed his mind to maybe when he feels nostalgic about his college years. He calls his friends, if they want to join him, which they do. Long-term student Olivier is joining the party as well. Following a long line of complaints about their fraternity, the police attempt to prohibit the party from happening, however it is held anyway. Lieve goes to the party, mainly because of Bram. Her friend, Elias, hesitated and would in turn arrive later. By accident and against his will, upon arrival Elias is registered as an aspiring member. After their orders are ignored, the police arrive to shut down the event. Elias sees Lieve going upstairs with Bram. Before he could follow, he was stopped by Beeksma and Noordzij, who inform him only members of the club have access to the upper level. Beeksma and Noordzij decide to prank Elias, but they accidentally let a cask of beer fall on a police car. Elias watches Lieve and Bram again, but Lieve is not impressed by Elias' appearance at the party. Irritated and angry, Elias goes outside and but bumps into a police officer, who hits him, making him turnaround and go back inside. A girl he met earlier tends to his wound. Olivier takes a picture of the wound and posts it on
Twitter, which frames Elias as a prominent member of the fraternity who was a victim of police violence, turning him into a hero. The conflict between the party-goers and the police begins to escalate, with the latter deciding to call in reinforcements and letting some of the party-goers go. Bram and Lieve almost have sex, but Bram backs out. Lieve is offended by this, and they argue. Meanwhile, Elias is having sex with the girl who looked after his wound, but they are interrupted when he receives a phone call from a sad Lieve, and Elias immediately goes to her. Some of the people, including Elias and Lieve, obey the police's order and leave the party, while some others remain. Elias changes his mind, and returns to the girl he was sleeping with. Bram is picked up by his wife and child. Olivier surrenders himself to the cops, hoping that the authorities won't shut down the fraternity. The police close the place anyway. The party ends in a confrontation between the remaining party-goers and the police. Elias sees the girl he was sleeping with being arrested, so he punches the police officer, which results in them both being arrested. The film ends with Elias and his new girlfriend opening a new bank account for a new fraternity named H.S.C. Mercurius, at which she is the treasurer. Olivier has been convicted and sentenced to community service, and begins to look for work. ==Cast==
