When a feisty little fox named Tod meets Copper, an adorable hound puppy, the two grow up together and vow to be best buddies forever. But when Copper is expected to take on his natural role as a hunting dog, he and Tod face the ultimate test of their unlikely friendship.
The film opens with Tod and Copper chasing a cricket together. They see a line of trucks bringing the county fair to town, and Copper is mesmerized by the sound of dogs singing together in an old school bus with "The Singin' Strays" painted on the side. The pair are eager to go see the fair, but when Copper's clumsy tracking skills disappoint his master Amos Slade yet again, the pup is tied up in the yard while Slade and Chief go to the fair without him. Tod arrives and pulls Copper's collar off, and the pair head to the fair.
