Ben Greene, an American television writer is brought to London to work on the popular sitcom "Tedford Gate." The star of the show is Carly, an attractive American actress who has created a successful new life for herself in England after being rejected by Hollywood. Her husband Allen is the producer of the show and is the archetypal proper English gentleman. Fiona, the pretty French makeup artist on the program, is selected by Carly as the ideal wife for Ben even though she has a crush on him herself. Over sumptuous picnics in the park and stolen moments at the production offices, the crush grows stronger between Carly and Ben and the admiration and intellectual attraction between Fiona and Allen is unmistakable. The culmination of the criss-crossing affections takes place at a seaside hotel and leaves everyone satisfied and happy for the time being.
Allen and Fiona are forced to question their commitment to each other when Fiona is offered work in Rome which would require Allen to part with his beloved England in order to follow her. Ben sacrifices artistic integrity to let Carly act and sing on the stage of his new West End drama, but that doesn't seem to be enough. She eventually runs away with Ben's Los Angeles agent, who offers her the Hollywood glitz and glamor that Ben no longer knows or wants.
