A controlled laboratory experiment goes awry as equipment malfunctions, and a laboratory catastrophe turns Tera Heart into some type of cross between a long-toothed vampire and Catwoman. Tera favors the feline and literally licks and paws her way into the curvy forms of her victims. The first to get sexually mauled is Anna Malle (great phonetic casting!). She and Tera partake in an erotic full-body tongue-lapping. their passion abated, Tera literally puts the bite on Anna, and Miss Malle, true to form(ula), discovers herself sporting an impressive pair of cuspids.

This highly-oral flick continues with moaning and cries of passion replacing dialogue. Mike Horner does Anna from behind on all fours (like the beast of burden that he is) and Yvonne provides a carseat b.m for Alex Sanders, amidst background howling, when a hissing and scratching Tera arrives to make it a macabre threesome.

Policewoman Felicia interrupts only to become one of the cat people, and part of an eerily lit Tera-Felicia-Anna trio (complete with fog effects). Mark Davis discovers himself trapped and, subsequently, impounded by the three human kitties. Most of his attention is given to Tera, but his finish finds its way dripping from Felecia's mouth. Brad Armstrong likewise falls under the clutches of Tera's sinewy embrace. He unzips her pseudo-bondage outfit to get at her pussy and ass with the ease of a panther in heat.

Occasional infrared views (from animal eyes), an excellent high energy soundtrack that fits the mood perfectly, and reasonably close attention to detail causes this to stand out and really purr. Should move faster than a cat on a hot tin roof.
