A beautiful showgirl, name "the Canary" is a scheming nightclub singer. Blackmailing is her game and with that she ends up dead. But who killed "the Canary". All the suspects knew and were used by her and everyone had a motive to see her dead. The only witness to the crime has also been 'rubbed out'. Only one man, the keen, fascinating, debonair detective Philo Vance, would be able to figure out who is the killer.

Margaret O'Dell, a blackmailing musical comedy star, is found strangled in her apartment, and four men come under suspicion: Lindquist, a half-mad doctor in love with Margaret; Cleaver, a politician whose career she threatened; Mannix, a fat broker with a jealous wife; and Jimmy Spotswoode, a young society boy Margaret was attempting to blackmail into marriage. Jimmy is arrested, and Philo Vance, a whimsical society man and amateur detective who is a close friend of Jimmy's father, is called in on the case. Vance proves the murderer to have been the elder Spotswoode.
