Jim Matthews, express agent in Red Rock, Arizona, and his daughter Alice, are watching anxiously over the bedside of Mrs. Matthews, who is very ill. An express box of money is now left by the stage and Matthews is ordered to guard it overnight. The "Arizona Kid," a notorious bandit, who has followed the stage and watched while they left the box, now gallops back to the rendezvous of his pals, tells them of the easy chance to rob the office and they start at once. Meanwhile Alice has sent her father for a doctor and is all alone with her sick mother.
