Sean Harrigan's a writer on the fringe of Hollywood, stuck in two relationships going nowhere: one with his girlfriend and one with his improv troupe, The Vanilla Gigolo Prescription. When movie star Finn Brooks, the former fifth Gigolo, enlists his help in dealing with a blackmailer, Sean must use his improv skills in ways he's never imagined, in a plot that isn't what it appears. Soon enough, Sean is faced with choices about how far he's willing to stray from his troupe in order to help a successful friend who's burned him before.
