“Billionaires’ Bunker” puts a dozen rich people in a hole and watches them fight. That premise is simple, and it mostly works.
Netflix’s 2025 thriller comes from Álex Pina and Esther Martínez Lobato, the creative team behind “Money Heist.” It follows a group of billionaires who flee to a luxury bunker called the Kimera Underground Park after an unnamed global conflict threatens nuclear war. Inside the sealed compound, an old feud between two families resurfaces, and the claustrophobic space turns into a pressure cooker.

The Cast
The ensemble sells the idea. Pau Simon plays Max, and Alícia Falcó plays Asia, the two leads whose families clash through the series. Miren Ibarguren plays Minerva, Joaquín Furriel plays Guillermo, Natalia Verbeke plays Frida, Carlos Santos plays Rafa, Montse Guallar plays Victoria, Agustina Bisio plays Mimi, Álex Villazán plays Ciro, Alicia Fernández plays Julia Baldini, Omar Banana plays Tirso, and Vito Sanz plays Nano Parker.
The actors carry the weight of a script that leans heavily on character friction over spectacle. That is a smart choice for a show about people trapped together, and it mostly pays off.
What Works
The tension is real. Eight episodes, each running a standard TV length, build resentment between the two families in a way that feels natural rather than forced. The bunker setting forces everyone to confront each other constantly, and the writers use that space well.
The show also knows when to slow down. It does not rush the feud or the fallout, letting the audience sit with the discomfort of being locked in a small space with people you despise. That patience is a strength.
Where It Falls Short
“Billionaires’ Bunker” is not subtle about its themes. The show is built around a feud between two families, and it rarely moves beyond that central conflict. The global conflict outside the bunker exists mainly as a backdrop rather than a driving force.
The show also struggles with pacing in the middle stretch. Some episodes feel like filler, stretching out conversations that could have been tighter. The finale wraps things up quickly, almost too quickly, after a few episodes that drag.
The Verdict
“Billionaires’ Bunker” is a solid, if predictable, entry in the genre. It is best when it stays focused on the people inside the bunker and worst when it tries to juggle the larger global conflict. The cast delivers consistently across all eight episodes, and the claustrophobia is genuinely unsettling.
The show earns a 6.4 out of 10. That score reflects a competent production with a strong core idea and some uneven execution.
