A tart close up of the suburban goldfish bowl, clever entertainment for lighter moments, and a good pick for the Dawn Powel market, without quite the bite. Rentals for your adult sophisticates; not for the watchful public librarian. Against a background of communting weekends, country club Sundays, bridge and Bundles for Britain, is told the story of Lynne and Park and their set who careen and carouse by night, with half-hearted flirtations along the way. Entertaining summer fare.
