In the season 5 episode 4 of Psych titled "Chivalry Is Not Dead...But Someone Is," Shawn and Gus become involved in a murder investigation when a man is killed in a museum. The victim, named Derek, was participating in a medieval reenactment and was dressed in full knights' attire when he was killed. The detectives on the case suspect that one of the other participants in the event may have been responsible for the murder.

Shawn and Gus, always eager to solve a new case, join the reenactment group and pretend to be participants in order to get a better look at the suspects.

They meet a group of knights who all seem convinced that one of their own is responsible for the murder, but they can't agree on who it might be.

As they gather more information, Shawn and Gus begin to suspect that the victim's girlfriend, who was also participating in the reenactment, may know more about the murder than she's letting on. They try to dig deeper into her past and her relationships with the other participants, but they come up empty-handed.

However, when they try to bring their findings to Lassiter, they find that someone has beaten them to the punch. The killer has confessed to the crime, throwing a wrench in Shawn and Gus' plans.

Despite this setback, Shawn and Gus eventually realize that the confession was fake, and they team up with Lassiter and the other detectives to catch the real killer. Together, they are able to bring the murderer to justice and close the case.
