Saw

Adam (Leigh Whannell) woke up and found himself trapped in an abandoned toilet. Opposite him is Lawrence (Cary Elwes) who has the same fate - their legs were tied with chains, and they were surprised to find a terrifying dead man lying between them. The dead man was dripping with blood, holding a video player in his left hand and a gun in his right hand. Someone put a tape into Adam's pocket, and he quickly put it in the VCR. The tape said that Lawrence must kill Adam before 6 o'clock tonight, otherwise the two of them will die together, and Lawrence's family will not be spared. The blood flowing from the dead man in front of him was extremely poisonous. A bloody death game begins. In the little time left, they must find clues and escape from hell. At the last moment, when they thought they would see the light of day again, a new round of nightmare had just begun.
