A deadly case of mistaken identity throws her into a desperate race against time. Her "daughter" is dying in the back of the ambulance. They have thirty minutes.
Their only chance is blocked on a mountain road by her ex-husband's new wife, all over a scratch on her precious new car. "Let that brat die," the woman says.
And she means it. Every second of pleading, every scream, just wastes more of that precious half hour. When the child's heart finally stops, the rage and blame are aimed at the wrong person. It's only when they peel off that bloodied Elsa mask that the real horror begins… Whose child did she just fight to save? And what will the woman who blocked the ambulance do… when she realizes who was inside?
