It is war! Noctis and Stella belong to the resistance movement CPR, which has set the end of oppression by the RSO to the goal. After several years of war, the CPR is planning an attack on the head of the RSO. The attack failed, however, Stella is captured and subjected to a brainwashing. Noctis and the CPR know that the RSO developed a program to control thoughts and for this reason they must liberate Stella. But they have heard, from reliable sources, that it is too late to save Stella and that she is under the complete control of the RSO. To survive and to protect the top secret plans, there is only one way out: To storm the heavily guarded research center and to kill Stella.
After Noctis has gone to the fight to free Stella and when she raises her weapon against him, he knows that it's true. The former friends are now standing face to face, with upraised weapons, to fight each other.
It seems that the RSO-Program to control thoughts is a success.
