Three years after their encounter with the Blades, the Nitros have broken apart and disbanded their team. Dante is now the face of justice in Lattice Light, while Nick tirelessly continues his pursuit of Sengre Malcolf, his family's killer. However, when a faceless thief begins a crime spree stealing dangerous technology, the Nitros find themselves teaming up once again to bring him down. With each passing day, this Mask appears to be further and further ahead of the Nitros, outsmarting and outpacing them in every way. Between the Nitros dysfunctionality, Steven's dark new habits, and Nick's degenerating Otrolium poisoning, can they possibly hope to stop a man who appears to have already won?
