Shark biologists Dr. Johan Gustafson and Dr. Mariel Familiar López investigate rising reports of bull sharks stealing from fishermen in Weipa, northern Australia. Could this methodical and radical shift in behavior provide new evidence of shark intelligence? To find out, the team deploys groundbreaking experiments and technology, including a new prototype diving cage.

Dr. Riley Elliott returns to Australia's Norfolk Island with underwater cinematographer Kina Scollay to see what happens when the island's tiger sharks go head-to-head with migrating great whites over an unusual food source: cow carcasses.
