Helen receives a cypher message about a jewel robbery and trails the yeggmen to their lair. Discovered, Helen is bound and gagged and thrown into a box car, but gets loose, and leaps to the ground from the speeding train. The crooks are captured, Helen's pluck wins Billy's heart, but, as usual, she refuses, with an eye on next week's adventure.
