Double-bill of horror. In 'Saw IV' (2007), two seasoned FBI profilers, Agent Strahm (Scott Patterson) and Agent Perez (Athene Karkanis) arrive at the depleted police precinct and help veteran Detective Hoffman (Costas Mandylor) sift through Jigsaw's (Tobin Bell) latest grizzily game of victims and piece together the puzzle. But the SWAT Commander Rigg (Lyriq Bent), the only local officer who has yet to experience Jigsaw's handiwork, is suddenly abducted. Thrust into the madman's harrowing game, he has but 90 minutes to overcome a diabolical series of interconnected traps - or face the deadly consequences. In 'Catacombs' (2007), a young woman (Shannyn Sossamon), on her first trip to Paris, hits a party in the Catacombs, the 200-mile labyrinth of limestone tunnels underneath the city that are lined with the remains of seven million people. Separated from her friends, she becomes convinced that someone or something is chasing her.
