In a Fire Island beach house, a brother and sister and their respective spouses gather to celebrate the Fourth of July. Anxious about their impending middle age, and wary of the world’s hidden threats, they fortify themselves against life’s disappointments—and their gay neighbors partying in the houses on either side—with food, drink, and an escalating series of wry observations and stinging barbs. This hilarious account of people struggling against their limitations is as perceptive about the way we live today as any comedy the American theater has produced in years.
