Elliot Kintner and his teenage daughter Ridley are heading to a weekend retreat at the remote estate of Elliot’s billionaire boss, Odell Leopold, when they accidentally hit a unicorn with their car. After discovering the creature’s blood and horn have miraculous healing properties, the Leopolds see a business opportunity instead of a moral problem. But the dead unicorn is not alone, and once its furious parents come looking for revenge, the estate becomes a savage battleground of corporate greed, family tension, monster-movie carnage, and very sharp magical payback.
