The fourth episode of CSI: New York finds Mac trying to solve the case of a man who confesses to murder and then dies, but things become complicated when they learn that his supposed victim is still alive.

According to CSI Files sources, "Time's Up" begins with a man running naked down the street. Panicked, he mutters nonsense under his breath as he darts through traffic and past shocked pedestrians. He is wearing a strange helmet and has electrical wires and gauges across his head, chest and arms. Stumbling around a corner, he catches sight of Mac and Flack about to enter the precinct. Seeing Mac's badge, the man hurries toward them, covered in blood and clearly on death's door. As he clings to Mac in his final moments, the man confesses to the murder of Kevin Moody, a college student at Chelsea University. With his last breath, he whispers something in Mac's ear.

Flack and several uniformed officers rush down the hall in the Chelsea University dorms. Flack forces his way through the door of a specific room and hurries inside. There is no body, no sign of a struggle. The sound of a shower running draws Flack's attention, and he bursts into the bathroom, much to the surprise of its occupant. Flack has found Kevin Moody, but despite their John Doe's murder confession, the young man is alive and well.

Mac and Hawkes process the John Doe, looking at the deep wound on his neck and the contraption he was wearing. Hawkes wonders aloud whether the man might have been insane. Mac sees Flack arrive with Kevin Moody and suggests that they ask him first. Looking at the body, Moody claims that he's never seen the man before. Mac tells him about the murder confession. Moody says that the man was obviously mistaken, but Mac corrects him. Technically, he explains, they wouldn't know for sure until the following day. Their John Doe told Mac that he had travelled through time, and that he had killed Kevin Moody in the future.

Meanwhile, Danny and Stella work with Detective Angell on the case of a college student who died in a deli. The waitress tells Angell that the young woman seemed to be having a spontaneous orgasm right before she died, drawing the attention of the other patrons. The busboy says that there was a young man sitting across from her in the booth--a young man who made a run for it when her ecstasy turned into agony and she began to take her final, panicked breaths.
