On a steamy summer night at the Greek seaside, full of music, dancing and taverna food, suddenly a sudden mist descends and strange creatures plague the city, attacking people and drawing others into the sea with strange dreams. A group of musicians join forces with a lost sailor in search of his wayward Greek father, along with a waitress, a bodybuilder, their granny, some local criminals, and an undead priest - banding together to fight back against the otherworldly invaders.
