Ulises Albet, a former tech prodigy, lives isolated from the world, far from technology and haunted by a personal tragedy: the death of his little sister ten years earlier.
When Samuel, his former friend and partner in a promising start-up, reappears with a disturbing message, Ulises returns to the city to meet him.
Their reunion lasts only seconds: a woman bursts in and murders Samuel in cold blood. Ulises runs.
During the week of the Mobile World Congress, trapped between a police manhunt and his own past, Ulises must decipher a new technology — one he helped create — if he wants to stop a threat that is already in motion.
