A Dallas-type plot pits big-business baron Roy Singleton with a young farm family, the Nobles. For quite a while, Singleton has tried to take their property, and now he seems to have found the answer. The old deed set the property line ""five chains from the northernmost granite rock."" Singleton and his surveyors have measured, and decided that the property line should be 100 meters south. Were this to be true, the Noble family would lose their only access road. In confidence, Mr. Noble decides that, if the property line is where Singleton insists, maybe the solution would be to build another access road. Paul and Leona, the youngest of the Nobles, get a trundle wheel to accurately measure how long that road would be. But all along, Singleton is watching them–and plotting. (Concludes in next episode.)
