In post-9/11 New York City, an eclectic group of citizens find their lives entangled, personally, romantically, and sexually, at Shortbus, an underground Brooklyn salon infamous for its blend of art, music, politics, and carnality.
Based on Michel Houellebecq's controversial novel, Atomised (aka The Elementary Particles) focuses on Michael and Bruno, two very different half-brothers and their disturbed sexuality. After a chaotic childhood with a hippie mother only caring for her affairs, Michael, a molecular biologist, is more interested in genes than women, while Bruno is obsessed with his sexual desires, but mostly finds his satisfaction with prostitutes. But Bruno's life changes when he gets to know the experienced Christiane. In the meantime, Michael meets Annabelle, the love of his youth, again.
David’s life is on the slide: he’s broke, in the middle of a divorce and ‘can’t get it up’. His girlfriend, Alice, is his rock, but the magazine she writes for is going down and the pressure is on to find a story. While job hunting online, David stumbles across the perfect antidote to his boredom: a ‘Swingers’ site. The resulting inbox of lewd invitations on the home-laptop justifiably upsets Alice, until she realises this could be just the ‘story’ she needs. The idea of uncovering the swinging scene causes quite a stir in Alice’s office and, much to David’s chagrin, she is urged to pursue the story. Their first reluctant foray is an hysterically low-rent initiation, however, an unexpected upturn for David’s manhood is all the extra encouragement they need. As events accelerate beyond their control the once adoring couple become lost and fundamental questions are asked of their relationship.
An affluent, middle-aged couple's uneventful lives are forever changed when they move into an isolated house in the country and befriend an odd, younger couple.
