"To Protect and Serve" is the fifteenth episode of the science fiction television series 2002 revival of The Twilight Zone. The episode was first broadcast on November 6, 2002, on UPN.
Police officer Eric responds to a call of a woman screaming. When he gets there, he sees a pimp trying to kill a prostitute. He kills the pimp, saving the woman. But after the ordeal, Eric gets a call on his phone and the voice on the other end claims to be the pimp he just killed saying, "You didn't think it would be that easy. It's not over."
They drive the prostitute home but Eric still wants to talk to her, being curious about Rigo, the pimp. She tells him that Rigo had no gang and no friends. Eric realizes that he knows the prostitute as his old friend's sister.
The memory of shooting Rigo keeps haunting his thoughts. He gets another call from Rigo on the phone, confusing Eric again, because he knows that he is dead. Rigo tells him that he is after Carla, the prostitute.
