The canine departs and soon meets Chuckie, the young son of Denver football star Hal Devlin and his wife, Natalie. Bingo and the boy quickly form a bond, and the dog becomes the family's pet. However, when Hal is traded to Green Bay, the Devlins must move... and Chuckie's parents refuse to allow Bingo to come with them.
Bingo then begins an odyssey to find his pal Chuckie, encountering numerous, dangerous obstacles along the way.
