Antibodies director Christian Alvart takes suspense into space with this tale of two astronauts who realize that they aren't alone as they drift into the darkest corners of our galaxy. Awakening in their hyper-sleep chamber with no memory of who they are or what their mission is, disoriented astronauts Lt. Payton (Dennis Quaid) and Corporal Bower (Ben Foster) gradually surmise that they are the only ones aboard the darkened spacecraft. But how did they get here, and what are those strange sounds coming from the belly of the ship? The only way out of their hyper-sleep chamber is a narrow airshaft, and the only one small enough to climb through it is Corporal Bower. As the younger of the two space travelers shimmies inside, the older remains behind to offer guidance on the radio transmitter. But the deeper Corporal Bower ventures into the ship, the more apparent it becomes that something horrible has happened. Could it be that the survival of the entire human race rests in the hands of these two astronauts stuck on a lonely ship in deep space?
