In Los Angeles, Theodore and his team have no choice but to go into the lion's den to learn the secrets that have not only destroyed their lives, but perhaps the lives of an entire generation.
Their road leads to Cerberus. Can he, Jack, Ludwig, and Yuna Saki come back with the truth that Rhein Ruhr Industries is determined to keep buried? Once behind enemy lines, they uncover a plot that goes all the way to Ganymede and changes their objective to just one thing: survival. Meanwhile, on Ganymede, Rachel makes two shocking discoveries that change her mission completely: First, the alien robot has transmitted instructions that make the crew very nervous; second, the ground team has to face the fact that they are not the only ones out there in the darkness of the Jupiter system. She, Patrick, and Julie begin a desperate race to unravel the mysteries of the white rings and discover what the robot is really after.
