Simon Moussa is a formerly successful screenwriter who lives in London. He's single and earns his living by teaching in film school, until an old friend, Charlie, visits one day with a strange proposition.

Nick Stone is a handsome, rich and famous actor, who hasn't figured out how to be likeable in today's social-networking culture. Because Simon is openly gay and has a pristine reputation, Charlie thinks that if the two were to pretend to be a couple, Nick would gain credibility, become likeable again, and Simon could use this to re-start his flailing writing career.

The plan is simple enough, and all they have to do is get along for a year—but even the simplest plan can go drastically awry when personalities clash and the past shows up at the worst time.
