Murder mystery games are supposed to have all the fun of a real killing without all the mess and bleakness that comes with an actual death. However, in The Final Stab, someone isn't playing by the rules. From director David DeCoteau (Puppet Master 3: Toulon's Revenge), the film stars Jamie Gannon as one of several young adult pals who converge in a house for a murder-mystery weekend. But when the players really start turning up dead, the fun turns to terror. Melissa Renee Martin also stars. ~ Matthew Tobey, Rovi
