The Lone Ranger and Tonto were busy preparing supper when Dan Reid, the masked man's fourteen year old nephew, returned from a trip to the nearby town of Rockville and reined up hurriedly. He was in a blind panic to reach them, after seeing the red mask outlaw hold up the bank in Rockville. After a shootout in the street, Dan hid, and saw the Sheriff and a posse head out of town to trail the thief.
