Acting like she's in love with her handsome nightmare of a co-star--in a movie directed and produced by her complicated Hollywood royalty family--is Sloane's job. But what happens when the lines between script and reality get blurred?

Out-of-work actress Sloane Ford is in desperate need of something to do after losing her steady TV gig. When her famous family ropes her into working as a producer on their World War II-era romance, they neglect to mention that the film will be headlined by Joseph Donovan, her least favorite former co-star of all time. The roguish actor made her life a living hell the last time they worked together, using his movie star good looks and Irish charm to cover for his erratic professional behavior. On their new film set, he promises he's different now, but Sloane is far from convinced.

As filming gets underway, it becomes clear that anything that can go wrong will go wrong. When the lead actress is abruptly fired, Sloane agrees to step in and take over the role, and she starts to remember why she fell in love with acting in the first place. On camera, she and Joseph share an electric chemistry. Off camera, they've been honing their characters and, much to Sloane's surprise, growing closer. But playing the role of a woman in love with Joseph Donovan is a dangerous business, and the more time they spend together, the less Sloane can tell what's real between them, and what's just for show.
