Conwoman Modesty Blaine suckers Bret out of $1,000 and sets him up to be shanghaied. Bret escapes and follows her to the town of Paradise where she's selling cats to rat-overrun miners, and tries to get his money back.

Bret takes a player's diamond stickpin as collateral and is soon mistaken for the player by the man's gang... and Bret ends up planning the robbery of the Denver Mint.
