Abbott and Costello provide hair-raising and hilarious thrills tracking - and being tracked by - a killer in this slick murder-mystery spoof.

The scene is a swank hotel where a prominent lawyer is murdered. Bud Abbott is Casey, the house detective, and Lou Costello is Freddie, the bellhop. Although there are plenty of suspicious characters about the murder is pinned on Freddie, who sets out to catch the real killer and clear himself. The menacing Swami Talpur (Boris Karloff) heads Freddie's suspect list, especially when he tries to hypnotize the little bellhop into suicide.
