London psychiatrist Wesley Atherton is a man of science. He doesn't believe in love at first sight, but he's inexplicably drawn to a green-eyed American beauty he bumps into on the Tube. Just his luck that Katherine, a fashion design intern, has an engagement ring on her finger.
Surviving a deadly train wreck is the first sign his intuition is spot on. The second: a psychic who warns them the Reaper doesn't like to be cheated out of its quarry. The situation defies all logic, but a string of strange and lethal events convinces Wes that he and Katherine are living on borrowed time. Pitted in a battle against death itself, Wes will do anything, make any sacrifice, to protect the woman he loves.
