Shayne (Lloyd Nolan) is doing jury service, with Lillian Hubbard (Janis Carter) the defendant. A witness is killed in the court room by a mysterious man throwing knives. Shayne decides to investigate what is really going on even though it means violating the jury rules.
He sneaks out and with the help of reporter Judy Taylor (Marjorie Weaver) investigates a trail leading to a nightclub singer (Joan Valerie) and a club owner (Don Costello). Of course, Shayne can't let anyone know he is out and about, but Higgins (Phil Silvers) is out to get a photo of him!
A fine entry in the Michael Shayne series though not quite as good as earlier instalments, credibility is maybe stretched a little far with the many shenanigans which take place on the one night but the film is a fun watch.
