Hospital Massacre (also known as X-Ray, Be My Valentine, Or Else, and Ward 13) is a 1982 American slasher film directed by Boaz Davidson and starring Barbi Benton.

Its plot follows a woman who becomes trapped on an empty floor of a hospital, where a murderer posing as a surgeon attempts to kill her.

In 1961, an unpopular boy named Harold Rusk leaves a Valentine's Day card at the home of the beauty Susan Jeremy.

On Valentine's Day, Susan has Jack take her to a hospital to pick up the results of a standard physical exam, which her new health insurance plan has requested.

A janitor later finds Dr. Jacobs' body, and has his face dunked into a sink full of acid by the murderer after trying to follow him into a nearby storeroom.

The peculiarities of Susan's paperwork (which the murderer further sabotages after killing a pair of laboratory workers) cause Doctors Saxon and Beam to order that she be detained for observation.

Susan is pursued to the roof by the wounded Harold, who she sets on fire after spilling flammable liquid onto him during their chase, and sends him plummeting onto the street below.

[3] An overall score of 2½ out of 5 was awarded by Adam Tyner of DVD Talk, who wrote, "X-Ray is kind of dumb and ridiculous, sometimes deliberately and other times not so much.

[4] DVD Verdict's Tom Becker stated, "While it's fun for a while, X-Ray runs out of steam long before the ending, in which the killer is unmasked, to the surprise of probably no one.
