The world is ending and two billionaires drag their families to an underground bunker to ride out the nuclear apocalypse. But the lap of luxury quickly turns into a gilded cage as devastating family secrets, raging insecurities, and decades-old rivalries between the families erupt into chaos and violence. Their survival depends on the mysterious woman who runs the bunker, and the unexpected alliances that form in tragedy.  Billionaires’ Bunker is created by Álex Pina and Esther Martínez Lobato, the duo behind Money Heist, Berlin, and Sky Rojo. The series stars veteran actors Miren Ibarguren (Phenomena), Joaquín Furriel (The Kingdom), and Natalia Verbeke (Ana Tramel: The Game).
