After years on the run, the mystery man known as Trick is back, but not on his own terms. Trick finds himself trapped in a cage with four other hostages - all of them paralyzed from the neck down. When Trick realizes that one of the other hostages is an old foe, Detective Epperson, the two begin working together to uncover the connection between them and their captor - a masked man they suspect is the infamous Deathstalker Killer. Meanwhile, Agent Bobby Church of the FBI is investigating Epperson's disappearance and discovers the detective vanished while he had been following a lead in the Deathstalker case. The search soon has Church crossing paths with Epperson's former partner, Scott, himself looking into the abduction of his friend, Olivia. After Scott and Church discover cellphone pictures of Olivia in the cage with both Trick and Epperson, they know they must race against the clock to find the location of the cage before time runs out, and the hostages are executed one-by-one.
