While Big Bird is very happy with his true family, he still could not help but wonder where his real family has been all these years. He asks his old caretaker Granny Bird about their whereabouts and without a warning, Big Bird sets off with Snuffy to find the truth. He meets a little lost hatchling along the road as well as other bird families and guest stars while the Sesame Street gang once again get on their vehicles and Follow That Bird! Meanwhile, up in the skies is a much larger bird stalking the crew who has a keen interest in Big Bird.
