Synopsis:
Sam Tyler finds it difficult to separate a life-and-death hostage situation taking place at County Hospital from his own strange circumstances. Stressed about a phone call where he seems to hear his mother's voice in 2008 -- begging him to wake up, he and the rest of the squad are ordered to diffuse a potentially explosive face-off in which a crazed gunman is trying to force a doctor to reverse a dangerous operation on the renegade's brother. Sam, Ray, Annie and Lt. Hunt are all targeted in the madman's cross hairs, but as Sam and the 1-2-5 attempt to resolve the confrontation, he suddenly realizes that the clock ticking on the gunman's demands parallels another deadline that could spell the end of Sam Tyler.
