Returning to America after an extended stay in England, Cousin Beau Maverick (Roger Moore) is hired to take the place of a young English nobleman. However, he soon finds himself the victim of a kidnap and ransom plot due to his assumed identity.

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.
