After being separated from the world for ten years, the Gatekeepers and their closest allies finally come back through the mysterious doors.

Jamie is the first to appear, in a church called St Botolph's, somewhere in the northeast of England, located in a strange and seemingly hostile village.

Meanwhile, the executives of the now nigh-all-powerful Nightrise Corporation are in the ruins of New York attending a business conference named the "Endgame" where it is said, they will be given their rewards.

Richard discovers that the children who were supposedly injured by El-Akkad's forces and are being treated in a Nexus-run hospital are child soldiers, used by Tarik to fight the ruling military.

Sickened, Richard also discovers that the vehicle being used to escort him and Scarlett out of Egypt is equipped with explosives, in a plan to kill them and El-Akkad in the same attempt.

He changes the license plates and other details of the bomb jeep with another, and he, Scarlett, and Remy leave the fort, meeting a driver who is really El-Akkad.

Scott and Pedro come through a door in Italy, where they are immediately captured by the police working for the Old Ones and imprisoned in a castle.

Scarlett and Richard bury Remy and take his wallet, before arriving at Dubai Airport and meeting First Officer Zack Martins, formerly of Emirates, now a buyer for the childish and insane Sheikh Rasheed al Tamin.

There, Scarlett bets the contents of Remy's wallet on roulette and wins, but Rasheed disqualifies her and invites her and Richard to his palace for dinner.

But Rasheed's wife helps them escape, with Larry, and they race back to the airport, taking off and heading to Antarctica.

However, unable to find a door in the gold mine, they break out and, though Matt falls ill, manage to steal a jet.

Despite Lohan wanting to go to the United States and then return to Asia, Matt controls the plane and steers it towards Oblivion in Antarctica.

But on the way to London, they run into a village whose inhabitants have become cannibals, as well as being pursued by Commander Eleanor Strake, the Old Ones' chief servant in England.

Then they get to the Vatican where Pedro meets a family called the Riveras, the son of whom, Silvio, is a cardinal who is in the Pope's circle, as well as part of the Pontifical Commission.

Meanwhile, the World Army, led by Commander Cain, that has arrived in Antarctica, decides to launch an attack on the Old Ones, despite Matt advising otherwise.

This not only sets the sky on fire but it causes a great earthquake that kills the chairman and many of the Old Ones' servants watching Matt's torture.

The ground splits open and a chasm into space is revealed into which a third gate forms and all the Old Ones are banished into it, as well as some nuclear missiles which the human resistance has unleashed.
