Ari, an undocumented Mexican immigrant working as a dishwasher in Bilbao, flees the city after defending herself against a sexual assault by the man renting her a room. With nowhere to go, she arrives in a small village in Bizkaia seeking help, but ends up lost in the mountains. After a fall in the forest, she is rescued by Abel, a 75-year-old shepherd who lives alone in a dilapidated farmhouse. Despite his age and worsening hearing loss, Abel remains committed to a life shaped by hard work and survival. Ari offers to rent a room from him, and gradually their initial distrust gives way to an unexpected coexistence. In their isolated world, far from society, two lonely and vulnerable people begin to find companionship and shelter in one another. The appearance of a horse disrupts the fragile balance they have built. While Abel sees the animal as a source of income, Ari forms an emotional bond with it. The arrival of the police forces them to act together, strengthening a relationship born out of necessity but transformed by mutual care and affection. When Abel disappears into the forest after trying to set the horse free, Ari sets out to find him in the darkness. In doing so, she realizes that what began as a hiding place has become something far more meaningful: a place of belonging, protection, and shared humanity.
