A man on a bike pedals for his life, being chased by armed assailants. He reaches his apartment building, drops his bike and runs inside. He pulls a digital camcorder from his backpack and is able to email out its contents before the men break in and asphyxiate him. This man, it turns out, is Leonard "Diddle" Callahan, and a college friend of Gus'. Shawn and Gus attend Doddle's funeral, where the minister says Diddle died from a hit and run accident on his bike. There, Shawn discovers, that not only was Gus in a singing group, but he has been estranged from Diddle, Tony and Joon for years and refuses to say why. Shawn also notices a mourner with a scar on his face who seems out of place there. Tony and Joon are able to speak to Shawn alone. They tell him Diddle was way too careful on his bike to die in an accident. They believe he was murdered, and they hire Shawn to find out what happened.
