Jim Thaw runs an isolated general store in California. He occupies a position as agent for the Great Eastern Express Company, which in the west is a day job. One day the stage drives up and deposits a money box with Thaw with instructions from the general manager of the Great Eastern that it is to be held with him over night, adding that he must keep a careful watch as it is reported that Buck Brady, an outlaw, has been seen skulking in the vicinity of Thaw's store.
