What could be better than being asked to help head up a big project at work on her first day? Anything but being asked by her boss to pretend to be his girlfriend for the holidays. But when Ellie meets the crazy ex-girlfriend her boss is trying to avoid, she can’t help but agree to be his fake girlfriend.
Brady doesn’t mind being put in charge of the big Christmas gala at work, but when he's forced to work with his ex-girlfriend, he panics. He is clearly not thinking straight when he asks the new intern to stand in as his girlfriend for the duration of the holidays—to keep his ex at bay—but is pleasantly surprised when she agrees to the scheme.
Thrown together in mishaps and close encounters, Ellie and Brady keep up the ruse for family and friends. Balancing the fake relationship with real feelings, can they fool everyone around them, or are they just fooling themselves?
