The Treehouse

'The Treehouse' is a Spanish horror film written and directed by Luis Calderón. The film, which will open the 32nd edition of the Bilbao Fantastic Film Festival, premieres in theaters on May 8, 2026.

Ale, her boyfriend Jesús, and their dog Drago escape to the Zeanuri forest seeking disconnection. They find it, yes, but not exactly as they had planned: more than 20 meters off the ground, in a cabin hanging among the treetops, what seemed like the perfect plan for Instagram turns into their worst nightmare. One night, Drago starts barking as if he has seen the devil himself. Ale goes out to see what’s happening. And what she sees is Jesús falling into the void. Without a net. Without a second chance.

A year later, while everyone around her has moved on with the idea of "it was an accident, things happen," Ale has another theory. A much less comfortable one: there is something in that forest. Something that took Jesús away. And now she returns to Zeanuri, not to heal wounds or make peace with nature, but with a very different plan in mind. Because if there is a predator lurking among the trees, Ale has already decided who the prey will be this time. And, spoiler: it’s not her.

'The Treehouse' stars Sandra Escacena alongside Claudio Portalo and Kandido Uranga. The film also marks the debut in conventional cinema of adult actress Apolonia Lapiedra as well as singer Mala Rodríguez.
