Inside the antiseptic walls of a little Los Angeles hospital, Our Lady of Pain and Suffering, a surgeon, Dr. Daniel Jekyll (Mark Blankfield), noses around and discovers the secret to man's alter ego in the formula of a white powder. Nodding off one day, Dr. Jekyll accidentally snorts a sampling of the snuff which quickly transforms this shy, sensitive man into a wild, wide-eyed disco deviant with New Wave tendencies. To the shock of his boss Dr. Carew (Michael McGuire) and Jekyll's fiancee, Mary (Bess Armstrong), spoiled daughter of the head doctor, Hyde takes over by taking to nymph chasing and disco blazing. But the richest and sickest patient in the world is admitted and needs Jekyll to survive. Will Jekyll show up? Or will he go on to discover more perverse pleasure hidden in his Hyde?
