LOGLINE: Shawn and Gus' childhood bully, jockey Jimmy Nickels, comes back into their lives when he hires them to find out why his horses keep losing. But a simple horse whispering assignment turns deadly when a rival jockey dies on his horse in the middle of a race.
SYNOPSIS: Jimmy Nickels, Shawn and Gus' childhood bully, has called and is coming to see them at the Psych office. The guys are scared but determined not to give up their lunch money again, until they open the door to see that Jimmy has not grown an inch since they last saw him, which is one of the reasons he became such a successful jockey. He's come to hire them. He's been losing his races and he doesn't know why. Despite Gus' protests, Shawn agrees to take the case. He has felt guilty ever since he turned Jimmy in for hitting a teacher with a spitball, which led to Jimmy's expulsion. Shawn feels he owes him.
They go to the track to "talk" to the horses and discover one of the other jockeys, Juan Carlos, is having an affair with a married tall blonde woman. They also come across Henry, who is a regular there and introduces them to Phil Shershow, a lifelong bad gambler who's on a hot streak. Henry insists they have no case. Horses lose for all kinds of reasons, but as he says this, a race comes to a close and Juan Carlos falls off his mount, dead. A track photographer does CPR, but to no avail. The police suspect he had a heart attack but, from what Gus saw of the body, he thinks it's more likely the result of poison or tranquilizers. It turns out they are both right. There were so many drugs in his system, from barbiturates to horse tranquilizers, his heart gave out. Shawn still thinks there was foul play involved and tells them about the affair with the blonde. Vick tells Lassiter and Juliet to look into it before they close the case. Meanwhile, Shawn realizes he was wrong about Jimmy when they were kids. It wasn't Jimmy who shot the spitball at the teacher. There was a second spitter.
Back at the track, they meet Barry, the track announcer who tells them that the track is closing down and that Juan Carlos had taken all of Jimmy's good mounts before he died. Not only that but the blonde woman they saw with Juan Carlos is Janine, Jimmy's wife. With everything pointing to Jimmy, Lassiter and Juliet arrive and arrest him.
