Lisa and Dan have perfect jobs, perfect kids, the perfect home, and the perfect marriage. With a successful business and rock solid marriage, they believe their love to be invincible. So when they embark on a well planned SWINGERS weekend to celebrate their birthdays, they're in it for the thrill, fun and nothing more. Of course its all perfectly arranged and planned. Theyve rented a magnificent lakefront property, stocked the fridge with great food and wine, and drafted up a list of rules and regulations to ensure everything goes as it should. Theyve also invited the youngest, coolest and hottest couple they know. But when a third unexpected couple shows up, everyones well laid plays go awry. Three couples. Two nights. What could possibly go wrong!
