Longarm's caught in the cross fire between feuding neighbors. A feud over water rights has got neighboring towns on the brink of all-out war. After a territorial division split one community into two, the locals found themselves taking sides in a conflict that literally pit brother against brother. Now, Deputy U.S. Marshal Custis Long has arrived to encourage both sides to let go of their thirst for vengeance and let past injustices be water under the bridge. But what could be a watershed moment for the small community may instead erupt into bloodshed. With skirmishes turning deadly and a bushwhacker gunning for Longarm, this whole peacemaking venture may turn out to be a washout.
