When a part-time worker in a mental hospital meets his old girlfriend inside he is not sure at first is she is a patient. Their reunion is haunted and haunting, and from the memory of their past affair there unfolds a labyrinth which darkens from romantic obsession to feelings deeper and more disturbing.

This work is set deep in the Peruvian Andes, where five ill-prepared travellers - men and women with different values, temperaments and motives - find themselves trekking through one of the most exacting and beautiful regions on Earth.
