At the age of eight, Nathan had a "tunnel of light" near-death experience while trying to save a little girl. Pronounced dead, he inexplicably returned to life.
Twenty years on, Nathan is a brilliant New York lawyer, bruised by a painful divorce and barricaded into his job, far away from his ex-wife Claire and their daughter. At this point, a mysterious doctor enters his life. Doctor Kay claims he can foresee exactly when certain people are going to die. With all his life's cornerstones shattered by Kay, Nathan finally discovers why he came back.
