Jenn and Greg are in Deia, a coastal village on an island off the southeast coast of Spain, on their annual holiday to enjoy languorous, close afternoons by the pool, and relaxed dinners overlooking the rocks. But the equilibrium is upset by the arrival of their teenage daughter, Emma, and her boyfriend, Nathan. Jenn, in her early forties, loves her husband and her (step)daughter and is content with her life, she thinks. But when this beautiful, reckless young man comes into her life, she is caught by a sexual compulsion that she's seldom felt since adolescence.
