In a world where the boundary between reality and imagination blurs, a young girl named Anna, who faces challenges in her daily life and her relationship with her family, discovers a peculiar way to escape her monotony. It all begins when she starts drawing a mysterious house on a piece of paper, a refuge where she can find the peace that's missing in her life. However, what seems to be just a simple doodle soon comes to life, taking her to an alternate world where her fears and desires intertwine.
As Anna explores this new dimension, she encounters a strange boy who appears to be trapped in this creation. Together, they traverse dream-like landscapes, but not everything is fun and games; the house also harbors dark secrets that threaten to devour their happiness. Between fantasy and horror, Anna begins to understand that reality has its own shadows and that her drawings have power—the ability to affect not only her destiny but also that of those around her.
As the line between the two worlds fades, Anna must confront her own fears and traumas, discovering that the escape she had clung to has unexpected consequences. Struggling to undo the chaos she has unleashed, she is forced to choose whether to remain in this dream world or return to reality, finally facing the problems she has been avoiding.
