'The Beast in Heat') is a 1977 Italian exploitation film starring Macha Magall, and directed, written, and edited by Luigi Batzella.

[1] A beautiful yet nefarious female SS officer/doctor, Ellen Kratsch (Magall), creates a genetic, incubus-esque mutant human beast (Baccaro) in a castle in occupied Europe.

The beast is a rapacious, squat sex fiend, which she uses to torture and molest female prisoners as part of a new medical experiment.

Most, if not all, of the battle scenes showing partisans attacking the Germans were taken from a previous war film directed by Batzella, Quando suona la campana.

[7] Tim Lucas wrote in Sight & Sound that the film was "so reprehensible that there's not a single real name associated with it" noting the director Paolo Solvay credited as Ivan Kathansky and that the film "doesn't have anything as impressive to offer as the prodigiously endowed torso of Dyanne Thorne in the 'Ilsa' concentration-camp series, so its cup runneth over with mayhem instead.
