Beau Maverick wins ownership of the Silver Hill, a worthless ore mine. A crooked railroad agent named Shanks tries to cheat the townspeople out of their land by offering them a price that is well below market value. Beau convinces the town to relocate Silver Hill to a sheep ranch twenty miles away. The plan backfires when a new vein of silver is discovered in the supposedly worthless Silver Hill mine, thus enabling Shanks to claim the land without cost. The only hope is for the town to relocate back to Silver Hill before the railroad takes over the land.

Beau & Bart fight to escape a black hole - where money and people enter, but can't leave! The cousins have to sleep sitting up in Stop Gap's only watering hole, after saving from robbers the treacherous Wembly, who promised them free, comfy hotel beds - but knew the inn was full-up. Wembly's suspiciously tight with the mining town's telegraph owner, son of a Colorado Senator. Why is the town too small to have a bank, as its population and wealth mysteriously expand to infinity - and beyond?
