A well-known attorney is murdered at the Lost Caverns Hotel. Murder evidence points to Freddie Phillips(Lou Costello), a bellhop. and his friend, Casey Edwards(Bud Abbott), is the hotel detective. Many murders are committed and casts more suspicion on the bellhop. Swami Talpur(Boris Karloff) tries to hypnotize Freddie into signing a false confession, and then killing himself. However, the bellhop's below average mentality prevents this from happening. Because of the great success of "Abbott & Costello" Meet Frankenstein the year before, Universal decided to team their former horror star, Karloff with their top comics. Boris Karloff played himself perfectly and with the great talents of Bud & Lou, it is a must see Classic Comedy. It is well worth viewing and owning!
