Óscar escapes from rehab, and Mário wakes up with images that don’t belong to him — no memories of his previous life. Thus are separated the two brothers living on the outskirts of Mexico City. The latter encounters Lázaro, who becomes his mystic mentor: in the underground, countless portals open to the supernatural. Clemente Castor’s work has long explored Mexican youth and their tormented bodies — Cold Metal continues along that path.
