Billionaires' Bunker (Season 1)

Billionaires' Bunker (El refugio atómico, 2025) is a Spanish thriller series you can watch online on iFILM. As nuclear war erupts above ground, a handful of the ultra-rich seal themselves inside a lavish underground shelter.

On the screens, cities burn. Down in the concrete vault, an old grudge between two wealthy families flares back to life with nowhere to run. Money buys nothing down here, but resentment compounds fast. The cast includes Miren Ibarguren, Joaquín Furriel, Natalia Verbeke and Carlos Santos, and every resident turns out to be hiding something worse than the fallout outside.

Built by the team behind Money Heist, the show runs on the same engine: a sealed room, mounting pressure, betrayals and sudden turns. These people are used to controlling everything except a catastrophe, or themselves. Stream Billionaires' Bunker (2025) online on iFILM.
