When it rains in the city, a serial killer known as "The Judge" looks for his next strangling victim. For months, the madman has been stalking at night, leaving behind clues, but police efforts have been fruitless. Constructing a life-size dummy of the murderer, police Lt. Harry Grant is growing obsessed with capturing him, and always following Grant is the relentless reporter Ann Gorman looking to break the story, but the hunt continues.
