Two scientists working in an eerie New England mansion discover a parallel dimension. But the denizens of this other dimension prove deadly. Jeffrey Combs plays the surviving scientist whose mental scars land him in an institution. Barbara Crampton plays a psychiatrist who springs Combs to help her recreate the experiment. Disaster ensues.

A terrific discovery, From Beyond plays like a pulp Hellraiser. The transgressive practical effects proved delightful, and the cast straddles the fine line between EC Comics-style heightened performances and camp. Indeed, the entire film walks the tonal tightrope with success, save when a character produces a cartoonish explosive (complete with timer) to initiate the finale.
