Emily, an interpreter, 37, lives in her New York apartment during the week and in the countryside in Pennsylvania with her boyfriend Matt during the weekends. They renovate an old farmhouse, slowly; Matt, a graphic designer, is extremely particular about every detail.
In the city, Emily runs into an old friend from high school, wild girl Marissa. Marissa is having an affair with a younger man, Justin. The next day Emily and Marissa meet for a lunch, and Marissa gets straight to point: she would like to rent Emily's apartment on the weekends as a "love nest." Emily doesn't know how to refuse and reluctantly agrees. The apartment is empty nearly every weekend, and she could use the extra money - what harm could "a tenant" cause? The deal starts out simply, but soon Emily is bumping into the lovebirds at every turn. Everything becomes so much more complicated!
