A group of friends travels to a cabin in the countryside to celebrate Citlali’s birthday. Everything is ready—the food, the music, the laughter... but Citlali never arrives. Instead, Fernando shows up, a friend of hers whom no one knows very well, claiming that she invited him. As time passes, the unease grows. One of the friends, Alejandro, begins to feel they are not alone. There’s something in the air—a presence watching them. The tension rises with strange noises coming from the fields and the growing sensation that someone is observing them.
