Roy has not had a physical relationship with a woman for as long as he can remember. Egged on by Tom, he visits Katia, a Belorussian prostitute in Soho. Emboldened by his friend's actions Tom decides to start seeing Katia as well.

Meanwhile, Amber is attending a church group as she has taken a fancy to Phil, the local vicar. She persuades Tom to come with her to a meeting and, despite his natural cynicism, he begins to take an interest in Christianity. His newfound religious beliefs are naturally at odds with his newfound interest in Katia.

Tom and Roy's friendship is then threatened when Roy discovers that Tom is also seeing Katia. Can they both turn their back on the most affordably-priced love of their lives, or will their desire for Katia drive them apart? Show less
