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.
