Frank wants the missing squad car found ASAP. It was stolen as part of a contest. Local high school students are taking part in a scavenger hunt. Chris and Traci catch a young kid trying to steal a sign for the competition. His name is Troy. He's left alone during the week so his mom can work far away. The kid agrees to help the cops track down the scavenger hunters who swiped the police car.
Gail is still adjusting to the fact that a man from her past is now a colleague in blue. Nick is making every effort to get her to lighten up, but Gail turns down his request to get together to air things out. She can't, however, deny Frank's order for the two of them to hit the streets looking for the stolen squad car. Speaking of the stolen car, the team finally tracks down the two kids who swiped it. Unfortunately, they sold the shotgun that was inside to a former student. His name: Wyatt Cripton
Andy and Sam arrive at the high school to find Wyatt in the middle of an intense discussion with Stella. The kid is a little on edge. He fires the shotgun several times into the air of an empty auditorium before dragging Stella into a hallway that dead ends. Wyatt eventually lets Stella go. He's still armed, but not dangerous. Andy realizes that his shotgun is empty. This allows Sam the opportunity to approach and arrest the confused kid.
