A penniless sergeant in the Air Force, Joe Fitzpatrick (Glenn Ford), impulsively marries a feisty nightclub showgirl named Maggie (Debbie Reynolds), who thinks money is more important than love. When Joe is reassigned to a base in Spain, Maggie follows behind, bringing with her the flashy 1955 Lincoln Futura Concept that Joe won in a contest. Believing Joe married her for sex, Maggie forbids him to consummate their marriage for 30 days, which leads to a domino effect of trouble.
