As the Links family continue their voyage to Mars, they discover a serious problem - they don't have enough fuel!! Now, James must make the ultimate decision to save Leon and Noel...

Realizing that there isn’t enough fuel to reach Mars, James must make the ultimate decision... that is until Dolores stumbles across a hidden space station!

After defeating a mech, James opens up the cockpit and discovers that the pilot is actually a young girl named Rebecca Hunter. She attempts to blow up the mech, killing both of them, but James manages to escape, saving her in the process. With Dolores, the three head to an abandoned Energy Plant. There, James treats Rebecca with kindness, giving her food and allowing her to take a bath. However, she soon manages to cut off all the power and escape with Dolores. Will she make it back to her squad? Will James survive without any oxygen, or will he find a way out?

James, Rebecca, and Dolores attempt to find humanity. They eventually do, although it isn't whom James expected. Can James shake Rebecca's friends and still manage to drop her off safely? Meanwhile, Leon and Noel find a town thanks to a man named Nikolai. But, is he friend or foe? And, what plot does Cindy have in mind?

Nikolai captures Noel and challenges James to a duel. Will James be able to win? And, why does Nikolai hate James so much?

After waking up in a hospital bed, James informs everyone that Radium intends to drop the orbital elevator on Earth. The only way to stop him is to convince Earth and Mars to cooperate with each other. Will James be able to do it? And, with Dolores still out of commission, can James bring her back to how she was? Is there hope? Or, will Radium succeed?
