What happens at the end of Beware Boiúna?

Key details:

• Lena, the main character, reconnects with her brother and faces her grief, suggesting personal growth but not triumph over the creature’s power. - The final showdown takes place on a construction site, where human tools are attempted against Boiúna—but this only highlights how little control people really have in the jungle. - There's a standout sequence near the end where Lena is submerged in thick, muddy water with the snake circling—a visually striking moment that underscores humanity’s vulnerability. - The film ends without defeating the monster; instead, it underlines that the jungle—and Boiúna—are ever-present and untamable forces.

So, the ending doesn’t offer a clean resolution. Lena survives in the sense she’s alive and changed, but ultimate survival over Boiúna—nature’s primal force—is left unsettled.
