Great white sharks are pushing farther up the East coast than ever before and in far greater numbers leading to close encounters, forcing beach closures, and leaving locals wondering where the next attack could happen. Now, a daring team of shark scientists race to install high-tech receivers and tag as many great whites as possible before another harrowing incident rocks the country.

The physics behind the thresher shark's devastating tail strike has long remained a mystery…until now. For the first time ever, the discovery of a shallow-water feeding ground has made observing this behavior possible. Now, shark scientist Dr. Craig O'Connell and marine biologist Aliah Banchik dive into the direct line of fire as they attempt to reveal exactly how these predators use their tails to stun and kill.
