"Outstanding makeup and technology" – Boxoffice

Strother Martin (Cool Hand Luke) and Dirk Benedict (Battlestar Galactica) star in this eerie tale of a respected snake expert who masks a frightening desire to transmute a man into a king cobra. Realizing that his new lab assistant, David (Benedict), is the perfect specimen, the demented doctor begins administering injections of "immunization serum." Soon, David begins experiencing strange side effects: his skin is shedding while his body shape is changing. But before he realizes the horrible truth, the metamorphosis from human to serpent has begun. This thriller, directed by Bernard L. Kowalski (Attack of the Giant Leeches), also stars Heather Menzies (Piranha) and Reb Brown (Howling II and TV's Captain America).
