Wipeout

Wallowing in guilt for shooting an innocent boy with a ricocheting bullet when he used to work as an LAPD cop, PI Ethan Carr is hired by a distraught amnesiac who wants to find out who he is. An assailant firebombs Carr's Mini Cooper, and in the trunk cops discover a corpse--which is a dead ringer for the amnesiac. Several hours later the amnesiac is gunned down, and, to Carr's shock, another amnesiac, who is also a dead ringer, steps into Carr's office and wants to hire him to find out who he is.
