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 has a secret girlfriend that he has been keeping from Shawn but is finally ready to introduce him to Ruby. Shawn's first impression of her is a good one, but he insists on meeting her friends to vet her further. So he forces Gus to crash what he thinks is a picnic with Ruby and her friends Jessica, Derek, and Stu. But the guys soon learn they have walked into a river-rafting trip instead. Ruby is thrown at first, saying there is not enough room, but then relents and hooks them up with gear. Shawn thinks Ruby might be hiding something, and uses his "psychic" abilities to break the ice with her friends by "divining" Stu is the most experienced of the group. Gus uses a more direct approach and asks how they all met. Ruby says Derek and Stu met at a Wildlife Preservation meeting, which is ironic because Derek was a big game hunter back when he dated Jessica, who is Ruby's work colleague. What binds them all together is their interest in extreme sports. The group then hooks strobe lights to their vests in case they get separated. Shawn and Gus realize they are on a white water trip just before they hit the rapids, and they hold on for dear life. When they come out the other side, they realize Stu is missing.
