The Psych Halloween special, 6×03 ‘This Episode Sucks,’ airs tonight at 10 p.m. on USA! When the victim turns up with bite marks on his neck, Shawn, Gus and Lassiter all agree that the murderer must be a vampire.

Lost Boys alum Corey Feldman has a cameo as a bartender at a “night walker” bar and Buffy the Vampire Slayer (the 1992 movie) star Kristy Swanson appears as Lassiter’s new love interest—and the suspected killer.

Watch the trailer below:

Official episode synopsis:

Lassiter’s new relationship with a mysterious and beautiful woman is placed in jeopardy when Shawn and Gus are convinced she is a murderer – the same murderer responsible for the blood-drained body SBPD is investigating.
