Saw

Bodies are turning up around the city, each having met a uniquely gruesome demise. As the investigation proceeds, evidence points to one suspect: John Kramer, the man known as Jigsaw, who has been dead for over 10 years.

Special Agent Strahm is dead, and Detective Hoffman has emerged as the unchallenged successor to Jigsaw's legacy. However, when the FBI draws closer to Hoffman, he is forced to set a game into motion, and Jigsaw's grand scheme is finally understood.

Following Jigsaw's grisly demise, Mark Hoffman is commended as a hero, but Agent Strahm is suspicious, and delves into Hoffman's past. Meanwhile, another group of people are put through a series of gruesome tests.

Jeff is an anguished man who grieves and misses his son that was killed by a drunk driver in a car accident. He has become obsessed for revenge against the drunk driver, judge, and only witness who refused to testify; he has also become neglectful of his daughter. Lynn Denlon is a skilled surgeon that is cheating on her husband and suffering from depression. Both are abducted and brought to Jigsaw's warehouse, where they must play two separate games: Jeff must choose whether to save or let the people he holds responsible for the death of his son die, while Lynn must keep Jigsaw alive until Jeff completes his tests, or face the deadly consequences.

Detective Eric Matthews, along with fellow police officers and a SWAT Team, locate Jigsaw's lair and go to arrest him, but discover that his arrest is only a part of Jigsaw's plan. Matthews soon learns that eight people are trapped in an old house and are playing one of Jigsaw's games. One of them is his own son, Daniel Matthews. Eric learns that if he wants to see his son again, he must play one of Jigsaw's games as well.

Despite Jigsaw's death, and in order to save the lives of two of his colleagues, Lieutenant Rigg is forced to take part in a new game, which promises to test him to the limit.

After trying to kill Mark Hoffman, Jill Tuck goes into protective custody. Detective Matt Gibson agrees to take her into protective custody once she signs an affidavit, revealing that Mark Hoffman is the new Jigsaw Killer. Meanwhile, Bobby Dagen, a self-proclaimed Jigsaw Survivor, is put through his own series of tests, where he must save both his friends and his wife.

Two strangers awaken in a room with no recollection of how they got there, and soon discover they're pawns in a deadly game perpetrated by a notorious serial killer.
