On a remote Scottish island, Max loses his hearing in a boating accident. Struggling to make sense of his new life, and resenting being put into the 'special' class at school, he notices changes taking place after a new wind farm is constructed off the island's coast. People have become irritable and unpredictable, and acts of violence threaten to tear the community apart. For the turbines are being used to test out a new soundwave weapon. Unaffected due to his hearing loss, Max and his classmates must find a way to stop the out-of-control experiment before it has tragic consequences.
