Mark Evans travels to Western Australia, where seven people have been killed by sharks in the last three years. Authorities have implemented radical measures to catch and kill any shark they deem a threat. Evans wants to find non-lethal solutions to keep people — and sharks — safe. He enters the water to attach tracking tags to great whites; joins beach patrol teams searching for sharks; and tests a new “multi-spectral” camera that spots sharks from the air even when they are hidden several meters underwater.
