In a tony beach community outside the city, beautiful, twenty-two-year-old, Alex, is living in the richly-appointed vacation home of mid-fifties Simon, a wealthy, divorced businessman. Alex is hoping that their arrangement will become permanent. Having arrived in the city two years ago, Alex has burned many bridges, the latest being Dom, a middle-aged man whom she one night awoke to discover him strangling her. The next morning, she stole a large stash of cash from him, took off, later met Simon, and is now enjoying Simon’s pool, his painkillers, the beach – where she one day nearly drowns due to the riptide – and being his arm candy at various beach community parties with his wealthy middle-aged friends.
Yet Dom is outraged, inundating her with countless texts and phone messages, vowing revenge, all of which Alex nervously ignores. After all, she long ago spent all his cash and has no way to pay him back. So far, she’s pleased that Simon believes her many lies, including that she’s a college graduate whose mother is an art teacher. Unfortunately, she miscalculates one day while driving his car, hitting a guardrail and breaking a rear tail light, which she hopes he won’t be mad about. That night, accompanying Simon to a party, she meets Victor, the handsome, thirty-five-year-old husband of aging Helen, the parties hostess. When Victor playfully yanks Alex into the pool, Simon watches, unamused.
The next morning, Simon coolly tells her that their arrangement is over – given her behaviour at the party, the broken tail light on his car – and has his assistant drive her to the train station, but not before she steals some of his cash and his watch. Convinced that Simon merely needs a break and will want her to return to him for his annual Labor Day party in just six days, she first tries to call various middle-aged men whom she’s been with in the city – none of whom want anything to do with her. Deciding to bide her time for six days at the beach community, she finds herself at a house party for several twenty-somethings sharing a house, pretending to have been one of the many invited. But when she unwittingly sleeps with Matt, the boyfriend of a now enraged young woman, she’s kicked out.
