The summer is almost gone and the owners of Heidi's favourite goat decide not to send it anymore to the meadows to be sacrificed. It's a bittersweet day for Heidi and Pedro, who have fun in their last day with the goat but at the same time see their summer efforts unfruitful. In the very last moment, Heidi hides the goat at her grandfather's putting Peter's job at a stake, so the boy confesses where it is. When its righteous owner shows up to claim what is his own, Heidi manages to convince him to let the goat live.
