Eighteen years have passed since Angel, the Megalodon shark broke free of the Tanaka Lagoon and returned to the Mariana Trench. Meanwhile, Jonas Taylor-adventurer, has become Jonas Taylor, middle-aged father of two, overwhelmed by mountains of bills and the daily strife of raising a family. But life is about to change.

A Hollywood television producer wants Jonah to join his new survival series: Daredevils. For the next six weeks, two teams of crazy daredevils on a South Pacific Ocean voyage on-board a replica of a Spanish Galleon will try to outperform one another in front of the cameras.
Jonas needs the money, and the job seems easy enough-doing color commentary. But behind the scenes, someone else is pulling the strings. And before it's over, Jonas, Terry, and Mac will again come face to face with the most dangerous creatures ever to stalk the Earth.
