Motherless Maggie is content to play on her high-school baseball team, work at Mr. Sullivan's clam shack, and dream of a career in pro ball--but then, having yielded to the temptation to ""try out"" a beautiful Jaguar left invitingly on a beach, Maggie is taken over by the car's fabulously wealthy owner CoCo Rainbolt, a do-gooder who sings to prisoners and such. Instead of pressing charges on the car ""theft,"" CoCo takes up with Maggie and her father--but plans the outings her way; gives Maggie a dog--but continues to give her orders on its care; and offers her protege a job in her kennels, which Maggie's beguiled father forces her to take. Maggie goes along because an upcoming dog show tour will take her to Ohio where she secretly plans to split and join a women's ball team; but finally CoCo goes too far and Maggie, giving up her dream, is on the verge of widening her sights. Maggie's disabled, beer-drinking father is nicely drawn, but Corcoran is as heavy-handed with CoCo, who runs most of this show, as CoCo is with everyone else; and the conflict among the three makes for a fairly thin plot. Nevertheless Maggie's baseball interest combined with her likable good sense gives this a limited, topical appeal.
