Shawn takes an unsuspecting Gus to a crime scene where they find a man who has apparently overdosed on pills. Shawn, skeptical of the proclaimed suicide, requests to read the witnesses, but the only witness to the event was the man's cat. This is good enough for Shawn, who proceeds to haul the cat around and communicate with him psychically. Gus sees no need for their involvement in the case.

Despite Lassiter’s cessation, the man Sally was supposed to have shot remains in character lying on the ground.

Shawn’s consequential plans to take the rest of the day off are ruined when a histrionic man, Robert Dunn, comes to the Psych office for help. He believes that he’s being haunted by a homicidal ghost and is certain that one night in his house will be enough to convince Shawn that something is out to get him.

He’s quite busy with relationshipsa "that means trying to patch things with his separated wife and tolerating interactions with partner Juliet.

Juliet goes to Shawn for some help finding a missing teenager, Malone Breyfogle.

An examination of Malone’s room indicates that he’s involved in something shady. Furthermore, they suspect that he can be found at TriCon, a comic book and science-fiction convention. This is good news for Gus, who is a comic book enthusiast himself. Lassiter and Chief Vick are out of the office and driving their way to a seminar together.
