Teenager Ridley is forced to spend the weekend with her workaholic father Elliot in the company of his boss's family — the terminally ill head of a pharmaceutical company. On the way to the family's country house, father and daughter suddenly hit a real unicorn. After killing the suffering animal, Elliot loads it into the car, and upon arrival, it turns out that it has come back to life and its blood has incredible healing properties. While the greedy rich family plans to monetize the discovery, Ridley discovers that unicorns are cruel and vengeful creatures.
