After a night of dancing and passion in a nearby town, Jack suggests to Joan that they find the treasure themselves before handing over the map. Zolo's men enter the town, so Jack and Joan steal a car to escape—but it is Ralph's car, and he is sleeping in the back. They follow the clues and retrieve the treasure: an enormous emerald called "El Corazón" ("The Heart"). Ralph takes the emerald from them at gunpoint, but Zolo's forces appear, distracting Ralph long enough for Jack to steal the jewel back. After being chased into a river and over a waterfall, Jack and Joan are separated on opposite sides of the raging river; Joan has the map, but Jack has the emerald. Jack directs Joan to Cartagena, promising that he will meet her there.
