This feel-good ensemble comedy tracks a quartet of suburban siblings and their families over the course of a single summer. Middle-manager Gil Buckman struggles to reconcile his ambitions at work with his loyalty to his family, particularly to his troubled son Kevin. His divorced sister Helen has a sullen and withdrawn son and a sexually active teenage daughter. Gil's other sister, Susan, is a schoolteacher married to an ambitious yuppie determined to make a genius of their three-year-old daughter. Their long-lost brother, the irresponsible Larry, has always been daddy's favourite and returns home with an illegitimate son named Cool.
