Oma und die bösen Buben (1967)

Pranksters Moritz Bolle and Max Sturbier plague their neighbors with cruel tricks - especially young record‐seller Brigitte, whom Moritz woos by posing as a Mozart‐loving engineer. When sharp‐witted Grandma Heimdall uncovers his lies, she tailors him a reckoning, exposing his scams and bringing their mischief to an end.
