Every two years in October - in 2008, 2010, 2012 and 2014 - a secluded beach on the central California coast has been the scene of great white shark attacks. Is it the same shark returning again and again? And will the attacks continue in October 2016? Dr. Michael Domeier believes the Surf Beach attacks may be more than a tragic coincidence. With the help of shark experts Ralph Collier and Cal Lutheran, and using satellite tags and DNA technology, he wants to out the killer once and for all. Produced by Shark Entertainment.
