Ten soldiers on convoy in Afghanistan suddenly find themselves lost in time. Somehow, they arrive in Earth's Paleolithic Asia. With no idea how they arrived or how to get back, the shock of the event is severe. They discover groups of the similarly displaced: Imperial Romans, Neolithic Europeans and a small cadre of East Indian peasants. Despite their technological advantage, the soldiers only have ten people, and know no way home. Then two more time travelers arrive from a future far beyond the present with a treacherous agenda that may very well lead to the death of the displaced in a harsh and dangerous era.
