After the global triumph of Money Heist, expectations were sky-high for the creators’ next move, and they return with Billionaire’s Bunker, a spectacular new series already sparking debate.
Set against the backdrop of World War III, the show follows the world’s wealthiest as they retreat into an opulent underground shelter, while the rest of humanity is left to fight for survival on the surface. A global hit and number one in several countries, the series has already entered Netflix’s Top 10 in the U.S., and buzz suggests it could soon climb even higher.

What Billionaire’s Bunker is about
The core of the plot is Kimera Underground Park, a huge underground complex dedicated to billionaires. While the outside world is in ruins, the elite live surrounded by pools, gyms, restaurants, zen gardens, spas, and psychological support services. Every detail is designed to simulate a normal life, but it’s an illusion of safety. The bunker spans 20,000 square meters and includes 45 ultra-luxury apartments, with prices ranging from 48 to 70 million euros. It’s a city within a city; a closed arena full of secrets and tension.
Even though the residents live in a golden cage, they cannot isolate themselves from the chaos outside. Screens inside the bunker broadcast live the collapse of civilization, increasing tension and bringing old grudges and family conflicts to the surface. At the heart of Kimera Underground Park, a war between two families breaks out, fueled by a painful wound from the past.

The recognizable style of Álex Pina and Esther Martínez Lobato
The creators of Money Heist are known for crafting images that not only capture attention but also invite reflection. Billionaire’s Bunker is not just a high-tension show but a story that investigates power, morality, and the true cost of luxury. An allegory and, at the same time, a powerful social fresco. The show raises direct questions: can one truly feel free when safety means isolation? And in a world where everything seems for sale, do loyalty and love still exist?
Does Kimera Underground Park really exist?
The key location in the show is Kimera Underground Park, a huge bunker with apartments worth tens of millions of euros. Promotional materials include the site bunkerkimera.com, which describes the complex as if it were real, with restaurants, spas, zen gardens, and a fitness center. However, this is a marketing strategy: Spanish media such as El País and Revista AD emphasize that Kimera Underground Park is a fiction created specifically for the show. This original campaign immerses viewers in the narrative world, blurring the lines between reality and fiction.
Why it’s worth watching Billionaire’s Bunker
It’s not your usual catastrophic thriller: it’s an intense story of power, money, and human nature put to the test. The creators of Money Heist have already proven their ability to captivate the global audience with gripping plots. This time, they take us to a place that seems safe but becomes a prison for the wealthiest. A narrative full of twists and moral dilemmas that hooks viewers from the first minute and keeps them glued to the screen.
