Folk song collector Dr. Šerk arrives in the remote village of Lesov. He is enchanted by the singing of sixteen-year-old Madla Satranová and he records her songs for radio broadcast. Šerk's friend, composer Jaroslav Klán, takes care of a group of orphans, from whom he has formed a choir. Šerk brings the orphaned Madla to him.
