The Seventies were sexy and sleazy. At the epicenter of it all was Plato's Retreat, the controversial, first-ever swingers club. In New York's conservative Upper West Side, Plato's embraced adventurous couples who came to dance, to swim, and… to swap. It was the start of a revolution. The brainchild of Larry Levenson, the self-proclaimed "King of Swing," Plato's Retreat quickly emerged as the mainstay of public sex for the "me" generation, welcoming anyone and everyone. For only $35, couples checked their judgments and pedigrees at the door; debutantes got it on next to bus drivers, as movie stars gave secretaries the "starlet treatment." For Levenson and others, Plato's was a utopia. However, this wild party did not last. American Swing brings this enigmatic epic of excess to the screen for the first time.
