The Onslaught

Shenandoah arrives in town and is seen by a man who says I've waited a long time to kill him. He then is drawn into a running gunfight in town. Upon leaving town he is shot in the head and left for dead. Strangers find him and bring him to the towns doctor. Shenandoah wakes up from the gunshot wound to his head with no memory of who he is.
