In this episode, Veronica is framed for creating fake IDs, and she sets out to find out who the culprit is. Meanwhile, the school guidance counselor, Rebecca James, interviews the people who were most affected by Lilly Kane's murder, and Logan's family dramas continue.
Guidance counselor Rebecca James, who used to date Keith, has gotten Veronica to come in for a grief therapy session because of a study she is doing. During the session, Veronica plants a stapler with a microphone on the desk. Meanwhile, Sheriff Lamb questions a student, Rick, on his fake IDs. When questioned further, Rick says that Veronica made the IDs, although she did not. During a locker check, Sheriff Lamb finds blank fake IDs spilling out of her locker, as well as four in her purse. Veronica is arrested and taken down to the station. At the station, Veronica confronts Rick. Rick says that an unspecified "they" forced him to blame Veronica. Later, Logan walks through the hallway and faces scorn and stares from the other students because of the incident with his father. Weevil talks to Rebecca while Veronica listens through her car radio. Rebecca shows proof that Weevil and Lilly were dating. Veronica wonders why Lilly didn't tell Veronica about her relationship with Weevil. Veronica meets with Rick in secret, and Rick tells her that a secret society called the Tritons decided to blame her. He is a recent inductee who was trying to get on their good side. Rick also tells Veronica that Duncan is part of the group.
Veronica puts a tracker on Duncan's car. Logan is suspended for a fight that broke out in school. Keith and Cliff tell Veronica that Rick's friend Tim's family is suing Veronica and Keith because they believe that Veronica created the fake IDs. Later, Wallace tells Veronica that he heard that a mystery locker at school dispenses fake IDs if the participant pays $250. Veronica positions a camera in order to watch the locker 24/7. Rebecca talks to Logan, and Veronica hears over the radio. Logan says that he blames Veronica for Lilly's death. Veronica and Wallace track Duncan to a mysterious location, which turns out to be a club. Veronica finds Duncan and asks him who the leader is, but he doesn't give anything up. Soon afterwords, Duncan brings Veronica a message from "The Great Triton," and she has to do karaoke onstage in order to elicit a response from the Triton leader. After the song, she meets with the supposed leader, but it is actually an impostor who reveals that a prank has been played on Veronica. Meanwhile, Rick has become targeted by the Tritons, who threaten him. Veronica hears Duncan's conversation with Rebecca. Duncan states that he has forgotten the days leading up to Lilly's murder.
Veronica is abducted and locked in her trunk. After being rescued by Wallace, she hears a Triton chant through her car radio. Veronica goes into the school and sees a ritualistic initiation meeting. She reveals herself and snaps a few photos. The Tritons give chase, but Veronica escapes before they can catch her. Veronica tries to match one of the Tritons to a person who operated the mystery locker, but finds nothing. Veronica visits Sheriff Lamb and makes him a deal—if she doesn't catch the thief by that day, she will plead guilty to any charges. She then asks Lamb to put a student's name into a locker and see what happens. Logan's parents have an argument that becomes increasingly heated before Logan blows up at his dad. Rick goes down to the station and Veronica explains the situation. Rick has been collecting the money from the locker through a hatch. He has been running his own fake IDs, and blamed the Tritons because he was angry at them for not asking him to join. When Veronica asks Rick why he blamed her, he states that it was because Keith's investigations made his family lose money and his parents get a divorce. Meanwhile, we hear a police report that Logan's mother, Lynn, has just committed suicide.
