Doctor of Horror (S06E10)

Richard and Charlie, two security guards at a morgue, are approached by a doctor who promises them five hundred dollars to assist in his bizarre experiment of capturing the souls of dying individuals before they ascend to heaven. When their supervisor discovers their scheme, Richard is compelled to eliminate him, but in a tragic twist, he also takes Charlie's life. The doctor manages to seize Charlie's soul, but that’s not the end—Charlie returns from the afterlife, seeking vengeance against Richard and the doctor for their betrayal.
