Steve travels to Patagonia, one of only two places on the planet where it is possible to watch killer whales hunting sea lions off the beaches.

Steve travels to Patagonia, one of only two places on the planet where you can watch killer whales hunting sea lions off the beaches. Here they launch surprise attacks on unsuspecting sea lion pups playing in the surf, before thrashing desperately to get back out to sea. It's risky business for both the killer whales and Steve. He only has five days to try to film this extraordinary behaviour, but these powerful predators haven't been seen for 10 days. While he waits, Steve gets the chance to meet a nosy armadillo and swim with some curious sea lion pups.
