Off the coast of New Zealand lies a hidden shark battleground, where three distinct groups of great whites organize into competing "houses" and may be competing with one another to gain control of a major seal feeding ground. Marine biologist Dr. Tristan Guttridge and underwater cinematographer Kina Scollay venture into the middle of the action on an epic expedition, using brand new builds and massive blood bombs to document this new competitive behavior. As they investigate, they uncover the possibility that these clans of great whites recognize kin and return season after season to their ancestral territories, raising the theory that these predators aren't solitary hunters, but rival dynasties at war.
