Two couples, one married and one on the cusp, (portrayed by Pretty Little Liars' Tammin Sursok, Jesse Bradford, and two other good-looking people) grow weary of life hanging out in the meatpacking district, antiquing in Rhode Island, and other pastimes people twice their age and income bracket usually enjoy. Still, the ladies are initially thrown when their menfolk suggest a shared-partner romp, but one, and then gradually the other, gets on board.
Before you can say "next stop, the Hamptons" -- which a character actually does say, to a cab driver, with gratuitous exclamation marks -- they're off to the shore for a casual sexcapade punctuated with mishaps and mistaken identity comedy that’s baseline Shakespearean, just dumber. Problem is, these adult female protagonists are considerably dimmer than their bejeweled cell phone cases, and both admit less than halfway through the movie that they only agreed to "sleep around" in order to win approval from their husbands. (Women hate sex, duh).
The whole film is pretty enraging, hideously acted apart from the main quartet, and ends up viewing like a racy Lifetime Original. Only the sheltered elderly and teens on Rumspringa would be scandalized.
