Die Freunde meiner Frau(1949)

Overly proper family man Walter Brinkmann is coaxed to a cabaret by free‐spirited friend Bernd. After a spoof of himself, Walter decides to embrace life’s fun side. With his wife away, he returns to the cabaret, where he harmlessly flirts with singer Fee Freiberg. His children and housekeeper secretly shadow him, and when his wife returns, she finds him surprisingly transformed, and then surprisingly grateful.
