A Scotland Yard detective investigates a series of murders of gangsters and girls. Inspector Perkins (Horst Tappert) is the prim and proper but cynical sleuth who knows the killings are drug-related. The trail first leads to Yvonne (Karin Huebner), a former victim of the white slave trade who seeks revenge on those who sold her into human bondage. Perkins must convince his stuffy superior Sir Arthur (Herbert von Meyerinck) that there is more to the case than is first apparent. Perkins dodges bullets, deals with double-crossing gangsters, and jealous career-minded agents as he searches for the man with the glass eye in this suspenseful crime thriller.
