In an alpine valley lies an idyllic village. High up in the mountains, facing each others across live two men: a "good grandpa" and an "evil man".

Two boys, Kekec and Rozle, come to serve a farmer, with a blind daughter Mojca, as shepherds. As the night falls, the two boys start talking about a woman who lives in the mountains and is supposed to steal children. Her name is Pehta. In the morning, Kekec, Rozle and Mojca go to an Alpine cottage and Kekec promises Mojca that he will find her a remedy for her eyes. As the girl is picking flowers, Pehta arrives and takes Mojca into her cottage. She wants to keep Mojca because of her singing.

A story of the witty boy Kekec, his friends and their adventures in the mountains of Slovenia during the summer.
