In the premiere episode, parapsychologist Dr. Sara Beckman is attempting to use a demon-summoning device, which serves its purpose all too well. The mysterious Raphael Cain shows up and rescues her, only to be accidentally shot by Sara for his pains. Goodwin whisks Raphael off, but needs Sara's car and apartment to buy him time to heal. The demons, led by Mallos and his ""assistant"" Vashista, see Beckman's device as a threat and try to track her down. Raphael manages to drive them off, but when he has to stop to rescue Sara, Goodwin is captured by the demonic duo.

In part 2, Mallos and Vashista torment Goodwin and use him as bait to draw in Raphael. The plan succeeds, but only after Mallos has sadistically ripped off Vashista's hand and sent her back to Hell himself. In their final battle, Mallos taunts Raphael with the fact that his daughter Kiyomi is still alive and out there...somewhere. He then manages to escape. Raphael and Sara recover Goodwin, and they decide to make Sara part of their team, bringing her scientific expertise on-board.
