After a young red fox is orphaned, Big Mama the owl, Boomer the woodpecker, and Dinky the finch arrange for him to be adopted by a kindly farmer named Widow Tweed. Tweed names him Tod, since he reminds her of a toddler. Meanwhile, her neighbor, a hunter named Amos Slade, brings home a young hound puppy named Copper and introduces him to his hunting dog Chief. Tod and Copper become playmates and vow to remain "friends forever". Slade becomes frustrated with Copper for frequently wandering off to play and puts him on a leash. While playing with Copper at his home, Tod awakens Chief. Slade and Chief chase him until they are confronted by Tweed. After a violent argument, Slade threatens to kill Tod if he trespasses on his farm again. Hunting season comes and Slade takes his dogs into the wilderness for the interim. Meanwhile, Big Mama, Dinky and Boomer attempt to explain to Tod that his friendship with Copper can no longer continue, as they are natural enemies, but Tod naively refuses to believe them, hoping that he and Copper will remain friends forever.

Leaving school for the day, seven-year-old Taichi finds a baby fox, abandoned by its mother alongside a road in rural Hokkaido. The two bond and Taichi decides to leave the fox with the police as a lost item. The policeman on duty takes a reluctant Taichi and the fox to the local Yajima Veterinary Clinic. It turns out that Taichi has begun to live with Ko, the vet, and his teenage daughter Misuzu after his free-spirited mother Ritsuko has gone to Micronesia to work as a photographer.
