This premise has been used before, even by the Twilight Zone. The issue of race is new here, but the person cursed by his actions goes back to the man who ran the little boy over with his car. A young man won't open his door to a desperate black man who is being pursued by skinheads. He is badly beaten and only asks to get in the car. The man drives away. The next day he begins to change, his skin getting darker and showing signs of being African-American. What can he do? There's something a bit weak about this episode--maybe it's too shallow in its thinking.
