The Earth is ruled by ruthless alien invaders who came to our planet seeking a mysterious power source known only as Sf-92. Now, one year later, the merciless aliens have crushed the planet’s armed forces and annihilated all freedom fighters. All but one: SGT Coleman is Earth’s last hope. If he can find Sf-92 then maybe–just maybe–he can use it against the alien conquerors and win mankind’s freedom. His search brings him to Clay County: a backward, redneck slice of the deep south that is completely unaware–or too drunk to care–of humanity’s subjugation by an alien army. Together with the unlikely allies of Clay County citizens Blake, Vern, Hot Dog and Root, Coleman sets out to find Sf-92 before the Earth’s otherworldly overlords, save mankind, and drink a few cold ones along the way.
