Shot in the head and left to die in the New Mexico wilderness, Frank Kavanaugh (Val Kilmer) wakes up in Black Point hospital. He doesn't know who he is, what happened to him or what he's doing in a desert town. Trying in vain to piece together his past, Frank is tormented by inexplicable flashbacks of a plot to assassinate the American president. Desperate to regain his memory, he turns to whoever will listen - but no-one, not even the secret service, can explain what's going on. Slowly but surely Frank begins to remember who he his and realises the terrible truth behind his visions.
