While at Potter's Field cemetery doing research for a story, reporter Bob Herrick sees a ghost that resembles him. He shakes the matter off, assuming that he's seeing things because he's overtired. But when he encounters the same ghost in his office, and at his apartment, he begins to worry. While his friends John Walsh and Mark Riceman scoff, his girlfriend Nisa King realizes that this is a doppelgänger who is trying to take over Bob's life by isolating him from his friends. As the doppelgänger grows stronger, presenting great danger to Bob and his friends, Bob tries to find out whose spirit the doppelgänger is in order to prevent it from taking over.
