Billionaires’ Bunker (2025 Spanish TV Series)

When the threat of nuclear war looms, a group of ultra-wealthy families sequester themselves inside the luxury refuge called Kimera Underground Park. Built to resist apocalyptic catastrophe, the bunker offers every comfort: spa, gym, cocktail bar, restaurant, and more. But beneath the sleek façade, old rivalries and bitter secrets simmer—especially between two families with a shared, painful history. As the world outside seems to collapse, tension rises among the privileged inside. Amid the paranoia and confinement, alliances shift, trust is tested, and no one emerges unchanged.
