Saw

Would you die to live? That's what two men, Adam (Leigh Whannell) and Gordon (Cary Elwes), have to ask themselves when they're paired up in a deadly situation. Abducted by a serial killer, they're both holed up in a prison constructed with such ingenuity that they may not be able to escape before their captor decides it's time to dismantle their bodies in his signature way.
