They're out of school, out on Nantucket ... and out of their minds! Anything can happen, and everything will happen during ONE CRAZY SUMMER! John Cusack and Demi Moore star as Hoops McCann, the scion of a long line of basketball stars who longs buck family tradition to be a cartoonist, and Cassandra Eldrich, the young woman who teaches him to follow his dreams even as she takes a hiatus from her own to help her grandparents save their house. Everything will turn out well in the end, but along the way no one and nothing is safe in this all-out, madcap comedy.
