Flying through the Russian Arctic, the team meets a family of red-breasted geese who are migrating to Lake Durankulak in Bulgaria. But the last in line is a cute baby goose who follows our big red Rocket by mistake! Rocket volunteers to lead the lost Baby Goose back home, and flies off with Baby Goose flapping along right behind. It's a thrilling coming-of-age journey past the swirling winter winds, over the Ural Mountains, and through a booby-trapped castle in Transylvania, but even a dreaded arctic fox can't stop Rocket from helping Baby Goose find his family.
