A year has passed since Ro Bernard escaped from the Midnight Scorpions, a clandestine group of mercenaries that exists in the outside world as little more than myths and rumors. Though haunted by the reprehensible acts she committed and witnessed as a member of the organization, her primary focus is keeping a roof over her head and food on her plate. A chance encounter leads her to Karin Cassels, whose son died in the Scorpions’ underground laboratory. While sharing details about her son’s research, Ro reveals the most disturbing information she has on the group. Their leader, scientist Dane Zedek, has been integrating cybernetic parts with human soldiers in the hopes of building a lethal army to help him achieve greater political power.

The women hatch a plan to take down the Midnight Scorpions with two ultimate goals: kill Zedek, and rescue Callum, Ro’s lover who was the first of the scientist’s experimental hybrids. For additional assistance, Dr. Cassels directs Ro to Reggie Quinn, a drifter who is no stranger to odd jobs and risky situations. Reggie negotiates a deal with Ro and agrees to join the cause in exchange for a percentage of whatever they loot from the Scorpions’ base.

They embark on an adventure throughout three warring countries to assemble their team and gather the necessary materials for their schemes. Along the way, Ro tries to fight her growing attraction to Reggie, especially as reminders of her unhappy past keep resurfacing. Love and redemption wait for her at the end of her mission to defeat the Midnight Scorpions…assuming she makes it out alive.
