But when Franklin tries his usual strategies with the Peanuts gang, he has trouble fitting in. That's until he learns about the neighborhood Soap Box Derby race - according to his grandfather, everyone loves a winner. He's sure that winning the race will also mean winning over some new friends. All he needs is a partner, which he finds in Charlie Brown.
