A true-to-life gangster movie stirs up an all out mob assault on Hollywood.

A murder is committed during the auction of a valuable statue. The prime suspect is Boston Blackie, whose reputation for living on the edge of the law makes him an easy target for the police. When the body disappears, Blackie must find it to prove his innocence.

A society sleuth sets out on the trail of a society matron's lost jewels.

The editor of a sleazy tabloid newspaper has been borrowing money from his lover, the wife of a rich theatrical producer, and promises to marry her when she gets a divorce. However, the husband refuses to grant her a divorce, and takes back all the money and jewelry he has given her. The editor sees her husband leaving her apartment and, seeing his opportunity, kills her, takes all his IOUs (and the jewelry) and frames the husband for the murder.
