In the distant highlands, a puma named Dusk is killing shepherds. Down in the lowlands, twins Iris and Floyd are out of work, money and friends. When the twins hear that a bounty has been placed on Dusk, they reluctantly decide they have to join the dangerous hunt, for a chance to win. But as they journey up into this wild, haunted place, they discover there's far more to the land and people of the highlands than they imagined. As they close in on their prey, Iris and Floyd are forced to reckon with conflicts both ancient and deeply personal.
