While on a vacation getaway in Palm Springs, two close friends, Lindsey (Jennifer Burton) and Geena (Monique Parent), spend their afternoons lounging by the pool while their husbands play golf. Seeking to spice up their routine, the women begin sharing intimate sexual fantasies, which rapidly escalates into a game of voyeurism, exhibitionism, and mutual boundary-pushing. Eventually, they draw Lindsey's husband Joe (David Elliott) into their escalating game. However, when Geena's strict, straight-laced husband Brad discovers the group's secret erotic dynamics, the game turns toxic, threatening both marriages and their long-standing friendships.
