Overview

Day One follows the story of Ulises Albet, a computer prodigy who left Barcelona and the world of technology after the death of his younger sister. Ten years later, a mysterious call from his former partner and best friend, Samuel Barrera, forces him to return during the Mobile World Congress. Samuel warns him that the world is in danger, leading Ulises to confront his past, technological advances, and the fundamental question: how far can we go without losing what makes us human?
