Shark Week- A great white shark researcher in the clear shark cage while a great white shark swims by.

Discovery's annual Shark Week is now in full swing. Up to bat tonight we'll see experts Ralph Collier and Brandon McMillian investigating the eerily similar 2010 and 2012 deaths in Surf Beach, CA on Return of the Great White Serial Killer.

In the exclusive clip below, McMillian and shark diving expert Jimi Partington have a run-in underwater with three massive predators around 16 and 17 feet long. Soon Lucy, their top suspect, the largest (and scariest) of all rises to meet them. The female monstrosity may bear the same name as New Jersey's famous elephant landmark, but you wouldn't want to run into this Lucy on vacation.

Take a peek at the jarring video below and watch Return of the Great White Serial Killer tonight at 9/8c on Discovery.
