It all started when a series of mysterious objects came plummeting out of the sky all around the world. By the time the government declared Martial Law, it was too late. The aliens had taken over, but a small band of humans vowed to fight back. Volunteering as a medic for an elite Special Forces unit, paramedic Greg Baker finds himself on a mission to transport a mysterious package into hostile territory. The contents of that package could be the key to driving the aliens back into space, but en route to their destination the team's helicopter is shot out of the sky. In the aftermath of the crash, the soldiers must fight their way through throngs of vicious extraterrestrials. Meanwhile, Greg must choose between completing his mission, and sacrificing the package so that he can return home to his beloved wife.
