Blondie's Secret (1948)

The 24th entry in the "Blondie" film series begins as Dagwood prepares for a long-delayed vacation with the family. His boss Mr. Radcliffe (Jerome Cowan) 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.
