As Reggie (Reggie Bannister) searches for the missing Mike (A. Michael Baldwin), Mike himself travels through various dimensions and across time itself to learn the origins of the Tall Man (Angus Scrimm) in hopes of discovering a way to stop him once and for all.

The series attempts to return to its roots a bit, dropping most of the humor from the last two entries, and trying for the off-kilter dream-state of the first film. The film is helped a great deal by use of a lot of footage that was filmed for the original back in '79 but that was edited out, so we get several scenes of the characters as they were back then. The origin of the Tall Man is finally established (somewhat), and that will either be a good thing or a frustrating thing for fans of the series. The sections focusing on Reggie tread much of the usual territory, and there are a couple of over the top gags that will delight or disgust. The ending this time is even more ambiguous than usual. The next (and final?) sequel arrived 18 years later.
