For millennia, the great white shark has reigned as the ocean's ultimate apex predator. But now, a new challenger is emerging: the killer whale. Around the world, sharks are washing ashore with their livers removed with chilling precision while in the Strait of Gibraltar, orcas are targeting sailboats - ramming hulls, crippling rudders, and sinking vessels. To investigate this alarming shift in behavior, Dr. Tristan Guttridge places himself directly in the path of an orca encounter, using their attacks on boats to reveal how these predators hunt and ultimately, how they may be taking down great white sharks.
