The bird-like Arni works as an all-rounder for a ramshackle travelling circus touring the countryside. The troupe is a family, where Árni is the only outsider. The boy lives his days in monastic simplicity, caring for the circus animals and carrying out the tasks assigned to him by the family. One day, a new python arrives at the circus. The animal arouses Arni's curiosity, and as he begins to tame it, he becomes more and more impressed in the process.
