Two musicians witness a mob hit and struggle to find a way out of the city before they are found by the gangsters. Their only opportunity is to join an all-girl band as they leave on a tour. To make their getaway they must first disguise themselves as women, then keep their identities secret and deal with the problems this brings – such as an attractive bandmate and a very determined suitor.
10 strangers are summoned to a remote island and while they are waiting for the mysterious host to appear, a recording levels serious accusations at each of the guests, including Judge Francis J. Quinncannon and Dr. Edward G. Armstrong, and soon they start being murdered, one by one. As the survivors try to keep their wits, they reach a disturbing conclusion: one of them must be the killer.
