A group of New Yorker caught up in their romantic-sexual milieu converge at an underground salon infamous for its blend of art, music, politics, and carnality.
Numerous New York City dweller come to the exclusive club Shortbus to work out problems in their sexual relationhips. Rob and Sophia are a happily married couple, except for the fact that she has never experienced sexual climax. This irony follows her to work because she is a couples counelor who frequently has to deal with the sexual issues other couples have. Two of her patients are Jamie and James, a gay couple who have been monogamous for five year and counting. James wants to bring other men in to the relationhip, and his own history with depression may hint at an ulterior motive. Ceth (pronounced Seth) may be the perfect addition to their family, but Caleb, a voyeur from across the street, may have his own ideas about that. Sophia visits Severin, a dominatrix with secrets of her own to reveal.
Set in contemporary New York City, Shortbus revolves around Sofia Lin (Sook-Yin Lee), who is married to the handsome but unambitious and slightly dim-witted Rob (Raphael Barker). She works as a couples counselor/sex therapist. She comes into contact with a couple: A slightly egotistical former child star Jamie (PJ DeBoy) and former prostitute James (Paul Dawson), the film's other lead character. At the outset, James suggests to his boyfriend that they open up their relationship to sex with others. During their first consultation, Sofia snaps, slaps Jamie, and then apologetically reveals her "pre-orgasmic" status. The couple suggests she attend a weekly social/artistic/sexual salon in Brooklyn called "Shortbus," which is hosted by drag performance artist Justin Bond (playing himself). Sofia slowly opens up to new experiences; this includes a friendship with a dominatrix who goes by the name Severin (Lindsay Beamish). Sofia's inability to achieve orgasm begins to cause conflict with Rob, who in turn begins attending Shortbus with Sofia.
James and Jamie meet a young ex-model and aspiring singer named Ceth (pronounced "Seth," and portrayed by Jay Brannan) and the three begin a sexual relationship. Meanwhile, James and Jamie's life is being closely watched by their across-the-street stalker neighbor, Caleb (Peter Stickles). Caleb fears the inclusion of Ceth in James and Jamie's relationship might break them up and thus destroy his ability to live vicariously through them, so he attends Shortbus, where he confronts Ceth. Sofia begins to go daily to a spa with a sensory deprivation tank to meet with Severin, and the two begin to have intense conversations. Severin begins to help Sofia loosen up sexually; Sofia helps Severin achieve a deeper human connection than she had experienced before. One evening at Shortbus, Severin discusses with Sofia the idea of giving up sex work to pursue her dream of being an artist. The two then have an unplanned sexual experience, and once again Sofia is left unsatisfied. Throughout the film, James is seen making a film about himself and his relationship. It turns out to be a suicide note. He attempts to take his own life and is rescued by Caleb, who calls for help, but is too embarrassed to wait with James for the help to arrive. He writes his phone number and email address on James' face while he is unconscious. When James wakes in the hospital, he calls Caleb. James goes to Caleb's home to be consoled, but does not contact Jamie or Ceth, neither of whom can understand why he wouldn't call them or come home.
There follows an interlocking trio of scenes showing connections between the characters' emotional problems and their sexual lives.
