David Tennant, Kelly MacDonald and Alice Eve star in this romantic comedy set in rural Scotland. When Katie (MacDonald) is jilted at the altar, she returns broken-hearted to her remote Scottish island home. But little does she know that Hollwood superstar Lara Tyler (Eve) has chosen the island as the secret venue for her wedding to her fiance James (Tennant). When the paparazzi gets wind of the location, Lara runs away in exasperation. Her management team decides to stage a fake wedding, hoping the paparazzi will fall for the deception and leave the island, and Katie is asked to don a white dress and walk down the aisle as a 'decoy' for the absent Lara. However, the path of true love is further complicated when attraction begins to grow between James and his decoy bride.
