In Trail of a Serial Killer (1997) Chris Penn is a burnt-out investigator who gets a second chance to track down the serial killer who got away--and, in the process, destroyed Penn’s marriage. We’d want to give the guy a medal for that, but pissed-off Penn starts looking into a group therapy session to try to uncover the psycho. There are plenty of red herrings and useless plot twists, but the film’s ending is still pretty amazing. Plus, you’ll become a serial masturbator once you see the twin thrills of Thea Gill.
