On a cold Christmas morning, a lonely train station worker in Chicago, Lucy, finds herself in a dreamlike situation that quickly turns into a hilarious tangle. After saving a stranger, Peter, from a fatal accident on the tracks, she ends up with this young man's life in her hands, but here's the twist: he falls into a coma. Confused, yet intrigued by the unknown man’s charm, Lucy shows up at the hospital, where Peter's family mistakes her for his fiancée.
Unable to unmask the truth and swept along by the whirlwind of Peter's family life, Lucy feels increasingly trapped in this sweet lie. As the days go by, filled with family dinners and laughter, she begins to fall in love—not only with the love attributed to a man who is unconscious but also with the warmth of the family that embraces her. However, her world will be shaken when Peter awakens. With a moral dilemma in mind, Lucy must decide whether to continue the charade or reveal the truth before it's too late. Amidst moments of comedy and a touch of romance, Lucy's story unfolds as a deep exploration of identity, love, and what it truly means to be in love.
