The first Slovakian colour film. A celebration of traditional Slovakian folklore and creativity expressed through a story of young love .

Strong-willed peasant girl Katka disobeys her father and heads to the city to work in a factory, where no one knows quite what to make of her.

The employees of the furniture company MARS welcome a rare visitor with hired music. Their boast that they would put together an orchestra is taken seriously, so they receive a small gift - musical instruments for thirty musicians.

The life on the poor Slovak hills, the lazy hills, where agriculture is at a primitive stage and where the shelves give a small harvest. Meanwhile, socialist industrialization is reaching an amazing boom in the valleys. Therefore, it is necessary to solve the problem of small farmers on poor farms and the lack of labor in ever-growing industrial enterprises. The film, based on the fate of Matěj Rendek, who returns to Slovakia after 18 years from America, and on the fate of his family, who have toiled for years on poor fields and slaved for a rich farmer, shows how this problem must be solved: an agricultural cooperative is established on the lazy hills, which, with the help of machines, can handle agricultural work better and with a significantly smaller number of laborers, and most of the lazy villagers leave to work at a large sawmill.
