Dagwood prepares for a long-delayed vacation with the family. His boss Mr. Radcliffe has promised the Bumsteads that there'll be no more postponements for their holiday. But when something comes up that requires Dagwood's presence, Radcliffe hires a couple of thugs to steal Blondie and Dagwood's luggage so that they'll have to stay in town. And that's only the beginning of the frantic fun.
