Death of a Unicorn

Elliot Kintner and his teenage daughter Ridley are spending a weekend at the estate of Elliot's boss Odell Leopold and his family—his wife Belinda and their son Shepard. While driving to their destination, Elliot accidentally runs over a unicorn foal with his car. When Ridley touches its horn, she experiences strange cosmic visions, which Elliot abruptly stops after he bludgeons the creature with a tire iron.
