The Outer Limits (1995)

Hope Wilson (Robbie Chong) knows there's something different about the bruised and breathless man who stumbles into the homeless shelter she runs with her mentor, Jack Parsons (Larry Musser). He looks like a junkie, but his hands are soft and his fingernails manicured. Tom Cooper (Dale Midkiff) doesn't know who he is, where he is and why two well-dressed men, Vincent (Michael Tiernan) and Cole (Brian Jensen), are chasing him. He only knows that the small metal case that he defends so fiercely contains five vials that hold all his memories, reduced to crystal form, as well as a specially designed injector that can delete or restore those memories.
