Colonel Joe Bishop made a promise and he's going to keep it; taking the captured alien starship Flying Dutchman back out. He doesn't agree when the UN decides to send almost 70 elite Special Operations troops, hotshot pilots, and scientists with him; the mission is a fool's errand he doesn't expect to ever return from. At least, this time, the Earth is safe, right? Not so much.

While the crew of the starship Flying Dutchman have been trying to assure that hostile aliens do not have access to Earth, the UN Expeditionary Force has been stranded on the planet they nicknamed "Paradise". The Flying Dutchman is headed back out on another mission, and the UN wants the ship to find out the status of the humans on Paradise. But Colonel Joe Bishop warns that they might not like what they find, and they can't do anything about it without endangering Earth.
