Ten soldiers on convoy in Afghanistan suddenly find themselves lost in time. Somehow, they arrived 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. These time travelers may have the means to get back, but they
aren't giving it up. In fact, they may have a treacherous agenda of their own, one that may very well lead to the death
of the displaced in a harsh and dangerous era.
