Grandpa, Kylian and I

The Karpíšek married couple, both doctors, are leaving for London for two months on business. They entrust their five-year old son Jožánek to the care of their neighbour, Mrs Pokorná. Jožánek is not pleased with the arrangement. He would rather wait for his parents at the house of his grandfather, a ferryman in Kralovice. On the following day after his parents' departure, the boy runs away to join his grandfather. His journey proves more difficult than he had imagined, but with the help of kind people he finally succeeds. The grandfather is a little angry with the boy but lets him stay. After that, Jožánek enjoys wonderful days: he catches fish with his grandfather, learns how to swim, sails on the barge and the donkey Kylian takes both of them to town shopping. But the boy also learns about a problem that worries his grandfather. A new bridge has been built across the river, people no longer need a ferryman, and grandfather must leave his cottage to move into an old people's home. Jožánek feels sorry for his grandfather and wants him to move his cottage to another place along the river and then move in with them in Prague when the summer is over. His grandson's words encourage the old man to act. He cancels his application at the old people's home and, together with his friends, pulls down his home to build a summer cottage from the materials. He moves to his son's villa in Prague, and in the garden house there is even enough space for the donkey Kylian. (official distributor synopsis)
