Aspiring interior designer Layla O'Reilly is dreading the Christmas time wedding of her cousin who's marrying Layla's ex-fiancé. Although Seth Murphy is the one responsible for introducing the bride and groom, she begrudgingly accepts his offer to be her date as she's out of options. Seth gets carried away at the reception and announces they're engaged, forcing a mortified Layla to keep up the pretense. But as the faux couple spends more time together they find themselves feeling something very real. Based on the book by bestselling author Denise Hunter. A Hallmark Channel original movie.
