Patsy and Michael and their friend Owl - a knitted toy that feeds on vole's blood - are fetishists, employed by clients to enact their most bizarre and buried desires. One day the pair arrange to meet a potential client in a City bar. Edward is a married city financier who employs the duo to accompany him on his encounters with Baby Girl, a fifteen-year-old girl he's having an affair with. The relationship between the four becomes intense, and as Michael becomes more and more interested in the world of commerce and finance, it merges with that of sexual deviance.
