With her older brother, Josh (Kevin Zegers), off at college, and her yuppie parents (Richard Karn and Cynthia Stevenson) obsessed with the new baby, young Andrea Framm (Caitlin Wachs) joins the junior high baseball team to escape the tedium of her home life. She's not very good, but luckily her sports-inclined golden retriever, Buddy, is a natural. Buddy also makes the team and becomes the star player. When the team gets into the championship game, a pair of zany scientists traveling in a laboratory inside a mobile home kidnap the pooch and his offspring in the interest of their experiments to clone sports-prone animals.
