While scouring the sewers of New York, Nick Tatopoulos discovers one of Godzilla's eggs has survived.

With Godzilla seemingly dead, the team journey to Jamaica to help the U.S. military investigate the ongoing disappearances in Jamaica.

After Godzilla battles robotic insects, the team encounter their creator: Cameron Winter, a powerful technology mogul and an old rival of Nick's from college.

As tension threatens to break up the H.E.A.T. team for good, major problems arise: a Giant Bat is terrorizing the countryside of Nigeria, the U.S. military has dredged the Leviathan ship from the bottom of the Pacific, and worst of all, the aliens are back.
