A young man leaves a barren, industrial world behind him as he enters a mysterious forest. Moved by curiosity, he goes deep into the forest until coming across a spot lost in time, known in the tales of old as the Hidden Spring, where there is a strange young woman who captivates him. They discover each other, but something in him reminds her of a macabre past, and their reality soon becomes a landscape of ruins where the machinery of the modern world has been reduced to echoes. The relationship between the two is mingled with the return of a violent legend apparently buried in time, one that transforms itself and is demythologized as the line that separates man from nature becomes utterly blurred.
