The Invisible Maniac

The Invisible Maniac

A brilliant but mentally unstable scientist is developing an invisibility serum. During the first test, the formula fails badly and acts more like a powerful narcotic/hallucinogen, causing him to have a psychotic breakdown. He murders several colleagues and is committed to a mental institution. He eventually escapes, returns to his lab, refines the formula, and successfully becomes invisible. Now completely unhinged, he embarks on a sadistic killing spree, using his invisibility to stalk, terrorize, and brutally murder attractive young women (mainly strippers and college students).
