As war breaks out among the colonies, a huge ship appears over the UPP mining planet Shānmén, releasing a horror that yields hideous transformations. Rescue is too far away, and the colonists' only hope appears in the form of the vessel Righteous Fury. It carries the Jackals, an elite mix of former Colonial Marines and Royal Marines. Led by Zula Hendricks, the Jackals seek to rescue the few survivors from the depths of the planet, but have they arrived on time?
