The active adventures of New York lawyer Matt Devijian, who goes to Miami to secure evidence in favor of Roy Stewart, a young Negro held for the murder of a senator. There he finds that Stewart wont talk, and Devijian plays cat and mouse with a nightclub dancer, the lawyer for the defense and the police. Eventually, after a series of minor and major (including two more murders) mishaps, Devijian gets the culprit. Embattled entertainment which is not without lighter touches.
