After being captured for a series of gruesome murders, Horace Pinker, a television repairman, faces execution by the electric chair -- but a deal with the devil allows him to come back as electricity. Once he changes into his new form, Pinker goes after the detective that brought him down, Lt. Don Parker, as well as Parker's adopted son, Jonathan. However, Jonathan's mysterious connection to Pinker through dreams might help track the killer's moves.
