From the description:
"In a stagecoach en route to San Francisco, Grace Rousselot is posing as a nun to drum up “donations” from fellow travelers. Across from her, Reuben Jones is faking blindness to prey on unsuspecting travelers. Both grifters are surprised to learn that they have competition, and even more surprised when their stagecoach is ambushed and robbed, leaving them both flat broke.
Not keen to discuss the robbery with the police, Reuben and Grace decide to work together to recoup some of their losses. Soon enough, what starts out as a practical partnership evolves into something more. And with the Chinese mafia hot on their heels, neither is sure just how far they can trust a man—or a woman—with a crooked heart."
