Returning to the site of his own 2009 shark attack for the first time, Paul de Gelder joins Madison Stewart to investigate a recent Great White Shark attack that occurred near Sydney Harbor, Australia - the first fatal incident in the region in almost 60 years. The dramatic encounter, which was captured on camera, was the sixth attack to occur in as many weeks. Within this aquatic arena, Great Whites contend with Bull Sharks, Tiger Sharks, and even humans in a colossal battle for supremacy. The unfolding saga raises the compelling question of who will emerge victorious in this intense struggle for dominance.
