Married couples David and Cathy Larson and Brad and Beth Youngquist live with their children in the relatively peaceful town of Pine City, Minnesota. David and Beth, after years of maintaining a platonic friendship, begin an adulterous affair with disastrous consequences. Through a series of scenes which all take place on or around a single bed, we see the painfully intense real-time unraveling of both marriages and, eventually, the construction of a very fragile but authentic new beginning for everyone concerned.
