Veronica is hired by Harry Greene, a Neptune High student whose dog Apache was killed in a hit-and-run. She tracks the car--a green Barracuda--to a blind old lady who preserves it because it was her late husband's. What she doesn't know is that her grandson, Liam Fitzpatrick, has been "borrowing" the car without telling her. He ran over Apache to send a message to Harry's little brother, Billy. Billy is terrified that if Harry finds out who did it, he'll spend his life in prison for putting an arrow in Liam; Veronica decides not to tell him.
Keith discovers surprising revelations about Kendall's past. And present--when Veronica was following the Barracuda, it was transportinging her and Liam to a house Kendall owns separate from the one she lived in with her husband. As it turns out, Keith has already found the house and is inside when they arrive. Fortunately, Veronica had taken the bullets out of the pistol he was storing in the Barracuda when she found it.
Weevil learns that the Fitzpatricks are abusing his old gang. Once he learns that Veronica just happens to have a copy of all the license plate numbers Thumper preserved, he is able to use that information to get the gang out from underneath their thumb.
Veronica makes a deal with Butters so that he'll help her get into his dad's office to retrieve Mac's confiscated cell phone interceptor: She promises that Mac will go to prom with him. She neglects to tell Mac the terms of the deal, however.
Wallace tries to get back together with Jackie, but she gives him some heartbreaking news.
- Keith discovers that, if Beaver and Dick die simultaneously, Kendall stands to receive more than eight figures.
- Veronica confronts Weevil about his possible involvement in the bus crash. She suggests that he intended to blow up the limo, but the bomb accidentally ended up on the bus instead. Weevil was close enough to the limo to know when it was approaching the cliff, and that he could have detonated the bomb with his phone without her knowing.
- Kendall was with Logan on the day of the crash, but kicked him out "before the sheets were dry," meaning she could have made the call that set off the bomb.
- Someone in a green Barracuda owned by Liam's maternal grandmother mooned Gia in the limo just minutes before the bus crash.
- Woody called Gia minutes before the bus crash to make sure she'd be able to pick up her brother, Rodney, from his piano lesson.
- Kendall is not who she claims to be. Her real name is Priscilla Banks--she killed the real Kendall Shiflett and two others in a car crash. She also owns her own house in Neptune.
- Liam's brother, Cormac, was Kendall's partner-in-crime. They were con artists, and Kendall took the rap for him, serving six months for wire fraud. The Fitzpatricks owe Kendall.
- Weevil helps the PCHers get out from underneath the Fitzpatricks' thumb by threatening to publicize the license plate numbers from Thumper's paddle. Veronica reflexively made of copy of the paddle when she stumbled across it in Ain't No Magic Mountain High Enough.
