近代劇《快乐的大人》是由保羅安卡 馮德倫 彭立為主演主要講述了:Mr. Tomasz, who sometimes introduced himself as Tomasz the Vagabond, was called by his friends Mr. Samochodzik. He owed his nickname to an unusual vehicle inherited from his uncle-inventor. This car, although ugly,"a cross between a canoe and a wheelbarrow", as the malicious people called it, had incredible capabilities: with a Ferrari 410 engine, it could run at a speed of 280 km per hour. Thanks to the screw used, it served as a motor boat. In this vehicle, Mr. Tomasz went to Poland to decipher another historical mystery, to catch thieves and smugglers trying to steal valuable historic items. Treasure hunting is great, but... it's better that no one interferes with it... In the meantime, some Danes and a suspicious group of Polish youth follow the trail of Mr. Samochodzik's search in the Teutonic castles and the headquarters of the Templars. To find the treasure you need a lot of knowledge, cunning and... a lot of luck. Who will have more?
