When a top-secret orbital research station is dragged from the sky by an unknown alien force, Steve Rogers finds himself caught between two global superpowers on the brink of war! But how does it involve Volkov - a decorated Russian officer he last saw in World War II, who disappeared on an ill-fated lunar mission over forty years ago? As the Russian army mobilizes to lock down the station's remote Siberian crash site, Captain America's mission is to find the survivors and bring them back alive - or silence them forever. Impossible odds in hostile territory are all in a day's work for Cap, but even he is unprepared for the horror that awaits them all in the icy wilderness. Because something has survived. Something alien. And it is awake!
