Hamster in a Nightgown - remastered version (2DVD) - DVD

Who knows how Kája Berka managed to forget his pyjamas when he went to visit his grandparents in Ružbach. His great-grandmother kindly lent him a nightshirt that belonged to his great-grandfather, who was known in the family as a ridiculous dreamer and an inventor of nonsensical objects. Only his great-grandmother considered her late husband, a professor at the local grammar school, to be an unrecognised genius.
After a night of dreaming in his great-grandfather's nightshirt, Kája completely agreed with his grandmother. Not only did he experience a trip to prehistoric times during his great-grandfather's lesson, but he also learned a crucial piece of information. His older brother Radim, a designer at a large car company, has long been struggling with his invention of revolutionary importance. Great-grandfather reveals to Kája that he himself once worked on a similar invention – a car that would run for free and without harmful emissions – and buried the important documentation in the garden.
