Basilio has begun to enjoy his stay in Los Angeles despite Zorro's interference. He is surprised at how well his war bonds are selling, for the landowners have decided to help support the Spanish government as much as possible. In fact, he and Capitan Mendoza have been able to collect three large chests full of gold. Mendoza suggests that they steal some for themselves before shipping it to Spain, but Basilio has a better idea. He wants it all. The two men construct a delayed action detonator designed to explode when the gold shipment is at sea so that the evidence of their crime will be destroyed. The next day the thieves pack the cases with rocks and load them on a cart that will take them to the ship bound for Spain. Zorro follows the shipment and narrowly saves the driver when the deadly cargo explodes ahead of schedule. Back in the pueblo, Basilio and Mendoza gleefully open the chests expecting to see their stolen gold. Instead, the boxes are full of sand and rocks, with a large "Z" inscribed in each of the lids.
