Zombie Sharks explores tonic immobility, a catatonic zombie-like state that can be achieved in sharks. This shark phenomenon has been studied by scientists for years, but a recent spike in orca whale attacks on great white sharks suggests that orcas have now learned how to immobilize and prey on great whites. Professional diver Eli Martinez looks to prove this theory by being the first person to induce underwater tonic immobility in a massive great white shark.
