Former lab
chimpanzee Bonzo, suddenly literate, escapes from a carnival sideshow. He lands in the college town of Pawlton, where young Betsy mistakenly believes that Bonzo is a gift from her grandfather Pop Drew, the college's football coach. Betsy wants to adopt Bonzo, but parents, Marion and Malcolm Drew, have reservations. A judge supports the idea and pretends to officially approve an adoption just to humor Betsy. Betsy writes to her other grandfather, millionaire Clarence Gateson, to inform him she now has a baby brother. Gateson is thrilled until he arrives in Pawlton and learns the truth. Gateson warms to Bonzo and takes him golfing. Discovering that Bonzo is a natural athlete, an idea is hatched for Bonzo to play quarterback for the college, where Pop is desperate for good players. Con men Edwards and Wilbur Crane kidnap Bonzo just before the big game and replace him with a chimpanzee that cannot play football. Before the con men can collect their bets, the real Bonzo appears and wins the game. ==Cast==
