This 20th entry in Columbia's long-running "Blondie" series finds poor Dagwood Bumstead (Arthur Lake) in financial trouble once again. Unable to obtain a raise from boss Radcliffe (Jerome Cowan), Dagwood begins "playing the ponies" at the race track, which gets him in trouble with the Law-not to mention his long-suffering wife Blondie (Penny Singleton). But salvation is at hand in the form of bank president Samuel Breckinridge (Grant Mitchell), who expresses a lot of gratitude when Dagwood saves Mrs. Breckinridge (Mary Young), likewise a horse player, from being arrested in a bookie-joint raid. The "regular" cast of the "Blondie" series remains the same as before, with the exception of Bobby Larson, who for this entry only replaces Danny Mummert as Alvin Fuddle.
