Shawn and Gus attend a Civil War reenactment rehearsal for the sheer pleasure of watching Lassiter have a nervous breakdown as he runs it.

When a scripted death turns real they end up donning uniforms themselves in order to find the murderer and perhaps prevent another.

Shawn reluctantly settles for a private client who claims a ghost has it in for him after Lassiter kicks Gus and him off the much more interesting case of a murdered psychologist.

The two investigations seem to be running parallel and Shawn may still end up solving the police's case.
