Gia Goodman is convinced she's being stalked, so Veronica takes the case. Gia received a video, just as her father had during the events of "Plan B". It's of her at her brother's soccer game. Despite her dad's orders to stop the investigation, Veronica tracks down the shooter – who turns out to be Lucky, the janitor at Neptune High and once a batboy for the Neptune Sharks.
When Lucky is arrested, Keith handcuffs himself to Lucky and throws the key down a drain. Keith starts to make progress getting Lucky to open up about his motivations, but Sheriff Lamb finds an alternate key and separates them before Keith can get anything useful. Intriguingly, Lucky's bail is paid by the Mannings.Woody Goodman enlists Keith's help in avoiding a scandal when he ends up with a passed-out woman in his motel room. Keith is photographed carrying her out; Woody blames him, saying he overstepped while investigating leaks. Keith tells the media the truth.
When Principal Clemmons cancels the prom because of drinking violations on the senior trip, Logan takes it upon himself to throw an "alterna-prom" in his Neptune Grand suite. At the party, Logan tells Veronica that he misses being with her and worries they'll fall out of each others' lives after graduation. Veronica panics and leaves, but comes back the next day to tell him she doesn't want to lose him from her life. Logan tells her the night is a blur… and then Kendall appears, clearly having spent the night. Veronica runs off in tears.
Woody's incorporation plan fails at the ballot box.
- Veronica finds out that she has chlamydia, a sexually-transmitted disease.
- Logan says that the sketch of the man who stole Cliff's briefcase looks like his father's cell mate.
- Woody enlists Keith in helping cover up an unconscious hooker (who he claims is a campaign staffer) that was in a hotel room with Woody. Keith is photographed carrying her out and Woody puts the blame on him; Keith gets a reporter to report what really happened.
- Near the beginning of the episode, Veronica reminds Logan that after they graduate, they'll probably never see each other again. At the alterna-prom, Logan expresses to Veronica how much he misses being with her, and how she broke his heart. Veronica gets nervous and bolts. The next day, she realizes that she doesn't want her and Logan to never speak again, so she goes to his hotel room and tells him that she wasn't ready for a relationship, but she wanted them to make a point of seeing each other after graduation. When she discovers that Kendall Casablancas is in the room and Logan tells her last night was such a blur, she starts crying and heads towards the elevator. He chases after her, starting phrases such as "Just so you know..." and "What I said..." But Veronica shakes her head at him and leaves.
- Gia received a DVD video of her brother's soccer game in the same way that Woody received one. This turns out to be from Tommy "Lucky" Dohanic, the janitor at Neptune High who used to be the batboy for the Neptune Sharks. He is arrested, but his bail is paid by the Mannings.
