Ten years later, a mysterious call from his former partner and best friend, Samuel Barrera (Asier Etxeandía), forces him to return during the Mobile World Congress. Samuel warns him that the world is in danger, but from what exactly? To find out, Ulises must confront his past, the relentless advances of technology, and an increasingly urgent question: How far can we go without losing what makes us human?

Day One will be filmed in some of Barcelona’s most iconic technology-related locations, such as the Barcelona Supercomputing Center – National Supercomputing Center (BSC-CNS), the ALBA Synchrotron, Talent Arena, the Collserola Tower, Pompeu Fabra University (UPF), and the 22@ District—spaces that perfectly reflect the fusion of innovation and tradition that defines the city.
