Margot Murray is a newly single, successful businesswoman with no interest in a cutesy seasonal romance after her breakup with her long-term girlfriend. Ben Gibson is an unlucky-in-love sweetheart in need of a woman to bring home for the holidays. Together, they make a pact: Margot gets two blissful weeks away from London in a picture-perfect manor, and Ben gets a fake girlfriend for his holiday at home with his family. Upon arriving to the manor, Margot meets Ben’s sister, Ellie, who is suspicious of the supposed relationship right from the start. Ellie intends to get to the bottom of their relationship, not being able to see how the two of them work as a couple. As Ellie and Margot grow closer, will Ben and Margot be able to keep the charade up, or will Margot and Ellie risk the chance at something real?
