As Professor Evans tries to unravel the mystery that is the masked Joseph, a horde of desert riders begin making their way to the Temple of the Beast, seemingly called by her captor.

Izaiah brings Alex and Bennett to an emergency meeting of the Medolians to discuss the worsening Joseph situation.

Back home in Arizona, while trying to discover if what happened in Africa was real or simply in his head, Bennett's past rushes to confront him.

Upon his return home, Alex sets about trying to find Melissa and regain his old life.

Professor Evans and Jeff, still on their own and studying the temple of the beast, are set upon by a traveler from the desert.

Following hours of agonizing torture—and yet somehow still alive—Alex and Bennett meet yet another creature from UnEarth and beg for their help.

Captured by the Wraithian cult, Alex and Bennett come face to face with an enigmatic man in a white mask who sheds some unwanted light on their situation.

Abandoned by Izaiah in an African desert, Alex and Bennett decide to take matters into their own hands and venture out to find help, soon realizing they probably should have just listened and stayed put.

The dig crew in Africa finally manage to open the onyx door at the top of the Dead Stairs and explore the mysterious reaches beyond.

Izaiah Ezekial, a man older than civilization, stands ready to recieve the two human delegates and deliver the news that they are not only technically dead, but now at the mercy of the powers of the afterlife.
