We call them the grays. For years, they lurked in shadows. For years, they struck from the dark. Kidnapping us. Torturing us. Studying us. Now they unleash their full fury. Thousands of their saucers attack Earth. Our armies crumble. Earth burns. Yet from the fire, heroes rise. Marco Emery. Addy Linden. Einav Ben-Ari. Names everyone on Earth knows. The names of legends. Names now whispered as a prayer.

They came from deep space. They came to destroy us. Fifty years ago bloodthirsty aliens devastated the Earth. Most of humanity perished. We fell into darkness. But now we rise from the ashes. Now we fight back. Marco Emery was born into the war. After his mother is killed, he joins the Human Defense Force, Earth's ragtag army. Emery must survive basic training, become a soldier, and finally face the aliens in battle. Against the alien onslaught, Earth stands alone. But we will fight. We will rise. We will win.

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.
