Humankind has been replaced as the dominant species on Earth by a race of monstrous insect-like creatures known as the Blue. Sleeper Yuji Kaido finds himself thrust into this nightmarish world, suddenly awakened after 22 years in suspended animation.
Yuji disobeys Marlene's orders by saving a little girl's life, and discovers a group of survivors hidden among the ruins of the city. Yuji makes a promise to the little girl, Yung, that he will protect her from the Blue.
The surviving members of the Sleeper Recovery Team must enter an abandoned communications tower that is now a Blue nest in a desperate attempt to contact Second Earth.
Marlene and Yuji now travel on foot towards Baikonur Space Base. The tensions between the two come to a head, as Yuji confronts the demons that now haunt him in this nightmarish new world.
Yuji is separated from Marlene and Dice amidst the confusion of a sandstorm. He is rescued from the desert by a band of nomads, and is befriended by Elena, a young nomad girl.
Marlene and Yuji arrive at Baikonur, only to find the space base in a state of chaos. The facility is crawling with Blue, and the computer defense systems have turned on their human counterparts.
The lives of the remaining recovery squad members are thrown into jeopardy when a renegade officer attempts to hijack the shuttle and escape on his own.
Yuji is rushed to intensive care after being attacked by a Blue aboard the shuttle to Second Earth. Now, Marlene must face an inquiry before the High Council and defend her recent actions on the planet's surface.
