Plot Summary

Dr. Gilbert McKenna (Robert Clarke) is a brilliant but troubled nuclear physicist whose personal demons have led him to alcoholism and professional disgrace. When a laboratory accident exposes him to a massive dose of an experimental isotope, the consequences are horrifying beyond imagination. While seemingly recovering in the hospital, McKenna discovers that exposure to sunlight triggers a grotesque physical transformation — his skin hardens into dark, scaly reptilian hide, his features become monstrous, and his mind regresses to a savage, predatory state.

Medical experts led by Dr. Buckell (Patrick Whyte) study McKenna’s condition and confirm the terrible diagnosis: the radiation has activated dormant evolutionary genes, causing him to devolve into a primitive reptilian creature when exposed to solar radiation. The transformation is reversible only through darkness — McKenna returns to human form when removed from sunlight. But with each transformation, the creature becomes more powerful and the regression to human consciousness takes longer.

McKenna tries to maintain a normal life by venturing out only at night, but the strain of his imprisonment becomes unbearable. He meets Trudy (Nan Peterson), a singer in a waterfront dive bar, and their nocturnal romance provides temporary solace. But McKenna’s daytime excursions become increasingly reckless. Each accidental exposure triggers the transformation, and the Sun Demon rampages through the city — attacking people, scaling buildings, and evading the growing police dragnet.

As the authorities close in and McKenna’s dual existence becomes unsustainable, the final confrontation plays out on the towering smokestacks of an industrial facility, where the Sun Demon makes his last, desperate stand against a world he can no longer safely inhabit.
