London, 1982. 41-year-old Father Jim Fitzsimmons waits nervously in the dark across the street from a line of "rent boys" that West London was known for at the time. Simon, a teenager among them, stands out. They make an arrangement and leave together. At his flat, Jim and Simon share a drink, an awkward dance but after Jim, half-drunk, kisses Simon, events take a turn. That night will change the course of both their lives forever.
