A doomed spacecraft. As the US's unmanned advanced aircraft Nighthawk mysteriously vanishes over the South Pacific, China and Russia's fleets race to find it first.
A race against time. Hot on their tails are Kurt Austin and the NUMA team, travelling from the Galapagos Islands to the jungles of South America to hunt down the missing rocket.
