There's no moral to the story, or at least there's no one-liner to sum it all up. And there's some really, really obvious sexual innuendo most animation producers, and the religious right, would shy from. The plot is an illustration of the point. They distract the crowd by pretending to fight but make off with a supposed map to the legendary city of gold. They end up captured on Cortez's ship on its way to Cuba and midway through enlist the help of his horse and all three escape to a rowboat.
Guards come and the two white boys on horseback are taken for gods.
The two begin trying to plan a way out but are caught between the two officials. Tzekel-Kan, in particular, is constantly trying to sacrifice people to them. Miguel begins to wander about the city, falling in love with the architecture and the people. Meanwhile, Tulio begins to fall in love with Chel, or at least she seduces him. Cheating seems to be a consistently good way to go.
