Humanity is faced with a new threat and an enemy beyond imagination.

Dr. Kate Warner managed to defeat a terrible virus - the Plague of Atlantis, although it managed to claim billions of lives. But she had no idea that the Atlantean conspiracy was much worse. People calling themselves Immari want to destroy humanity, saving the lives of only a select few, and found a new civilization. Their leader, the Atlantean Ares, doesn’t care about people at all; he wants to revive his race, almost completely destroyed by alien invaders. However, a new glimmer of hope appears: a signal from a potential ally. Dr. Warner and her team must delve into the Atlantean past, unravel their secrets, and try to save humanity from extinction. The final test awaits them.
