Donna and Dedron are beginning to settle into a new life together on planet Earth when they get the call about a new mission that they are needed for as members of the Defense Squad. The Remoir, despite having suffered a great defeat at the hands of the squad, are attacking innocent settlements yet again. However, when Dedron and Donna arrive at the base for a briefing, they find a message has been left for them from Perbron, the new commander of the Remoir forces. Perbron is ready to seek revenge for the defeat of his father, and he threatens to kidnap family members of all of the Defense Squad members. Although the Defense Squad’s mission is to gather intelligence about the Remoirs’ next move, Donna takes it upon herself to leave and check on her mother. Dedron goes with her, making them deserters from the Defense Squad. Can Dedron and Donna stop Perbron’s revenge by preventing him from kidnapping their loved ones? Or will they succumb to Perbron’s plan to watch each member of the Defense Squad face combat with Remoir soldiers?
