Bret Maverick takes down a money-hungry gambler in the town of Echo Springs. He befriends an old drunk, who turns out to be a successful judge. Maverick strikes a deal with the gambler, Phineas King, to merge the ""silver lady"" mine with ""the new hope"" mine.

Bart Maverick wins big, when he wins the ""Lucky Lady"" saloon in a card game. When Bart goes to Santa Leora to stake his claim, a beautiful Marquesa refuses to relinquish the property to him. Maverick encounters hurling knives, flurry of bullets and pounding fists when he tries to hold onto his newly acquired saloon.

Hired to protect a cattle drive, Bart dutifully chases Indians — while a masterful swindle takes place right under his nose.

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.

Thinking all's well with the world after he cleans up in a card game, Bart offers to help a troubled young woman.
