After an attempt by the UPMC to rescue Dr. Dunby fails, there is little hope that she will ever be rescued. Feeling that they failed in their mission at the Battle of Delpha to protect Dr. Dunby, Thomas and Black Squad set out on their own mission. They'll bring back Dunby or die trying.
Finding Dunby in a remote area of Krod, next to a military base, Black Squad's odds of returning with the doctor diminish with every minute they're on the enemy planet. Their ship to return home is destroyed, their communications are cut off, and they're badly outnumbered, leaving them to battle an entire base in order to survive and get off the planet.
