Boston is being terrorized by a series of seemingly random murders of women. Based on the true story, the film follows the investigators path through several leads before introducing the Strangler as a character. It is seen almost exclusively from the point of view of the investigators who have very few clues to build a case upon.

Gus Linden, former racketeer head of a Detroit local of the United Automobile Workers of America, A.F.L, attempts to destroy his successor, Blair Vicker, so he can put his old rackets back into the auto factories. Vickers fights him off, ultimately winning help from Linden's attractive daughter Barbara and from Joni Calvin, Vickers' moll.
