This is the comic tale of four identical pieces of red plaid luggage and one San Francisco hotel, in the spirit of Howard Hawks but made by Peter Bogdanovich. One bag contains secret government files, another has expensive jewels and a third has igneous rocks. It is unclear what is in the fourth bag, carried by the would-be erudite Judy Maxwell...but all four bags end up at the Hotel Bristol. Judy has a yen for food and Dr. Howard Bannister and no 'off' button. Dr. Bannister (deliciously deadpan and hunky, Ryan O'Neal) has a yen for igneous rock formations. When all four bags are hopelessly mixed up and Eunice, Howard's prim and bossy fiance (unforgettably played by Madeline Kahn) is kidnapped, only the long arm of the law, (i.e. the judiciary), can make any sense of the chaos. There are no palaeontologists or tigers but there are madcap antics, the obligatory San Francisco chase scenes and several clever one-liners.
