Shawn’s life hangs in the balance when, while working on a case involving an ice cream truck, he stumbles onto something bigger and more deadly.
Juliet and Lassiter meet Gus at a vehicle storage yard in the middle of the night. Gus received a message from Shawn telling him that he’d solved the case and to meet him there but Shawn has not shown up and Gus is worried. He should be. Shawn is currently bound and stuffed into the trunk of a moving car. Shawn remembers a lesson Henry taught him as a child, and kicks out the rear light of the vehicle. Through the hole in the trunk, he’s able to spot some landmark, and manages to text Gus cryptic descriptions of what he sees. Back at the storage yard, Gus is puzzled by the message. Lassiter finds blood on the ground and they realize Shawn’s been shot and kidnapped. Gus calls Henry, who arrives at the scene and insists on helping find his son. So Lassiter and Henry team up to decipher Shawn’s text and track him down, while Gus and Juliet retrace the steps of Shawn’s latest investigation.
Gus tells Juliet they were working on an ice cream truck accident. Shawn noticed a hole in the gas tank and fresh welding marks on the undercarriage of the overturned truck. He believed the truck was crashed on purpose and wanted to discover why. They found out who serviced the ice cream truck and spoke to a mechanic at the garage, who told them welding is usually used to repair a crack or to reinforce steel, but without looking at the truck in question, he can’t say for sure why the bottom had fresh welding. Juliet tells Gus she wants to interview the mechanic herself.
Meanwhile, Shawn manages to pop open the trunk and makes a break for it through the woods, being chased by the driver who happens to be the mechanic. Shawn remembers another one of Henry’s lessons about evading a pursuer and successfully loses the mechanic in the woods. He spots a gas station, and runs to the attendant for help but before he can fully explain what’s happening, the attendant smashes him over the head, knocking him unconscious.
