When a man returns to his beachside hometown in Australia, many years since building a life for himself in the U.S., he is humiliated in front of his teenage son by a local gang of surfers who claim strict ownership over the secluded beach of his childhood. Wounded, he decides to remain at the beach, declaring war against those in control of the bay. But as the conflict escalates, the stakes spin wildly out of control, taking him to the edge of his sanity.
