After witnessing the murder of his wife and young son at the hands of Henry Caine (Craig Fairbrass), who then turned the gun on himself, Abe Dale (Nathan Fillion) is so distressed that he attempts to take his own life. A near-death experience follows that leaves Abe with the ability to identify those who are about to die. He acts on these premonitions to save three people from death, among them a nurse met during his recovery, Sherry Clarke (Katee Sackhoff).
