A wacky cult leader with strong telekinetic powers dies unexpectedly.
But not before he transfers his diabolical spirit into sweet nurse Sherri (Jacobson)...who then proceeds to knock off all those who had a hand in the death of her occult possessor!
Good natured low budget effort is skimpy on actual scares, but seems to have an entirely serious cast working to give you all they've got, including Sherri's quirky 'possession' scene with a green light, Sherri pitchforking one of the hospital's physicians and Sherri hacking her own boyfriend with a meatcleaver. Ah, Asclepius...
The amusing PSYCHO explanation/wrap-up (given by a blind, black football player!) must be seen to be believed.
Also known either as Nurse Sherri or as Beyond the Living.
One of the last projects for genre director Al Adamson, who gave us Blood of Ghastly Horror (1972) and Horror of the Blood Monsters (1970).
