Billionaires’ Bunker Ending Explained
The series opens with Max killing his girlfriend in a car accident, going to prison and starting a fight club and eventually getting out before being whisked away to an underground bunker by his wealthy father as World War III breaks out. Inside, he reacquaints himself with his family and Ane’s as well, who are still unsure about where they stand with the man who killed their daughter.
Of course, as we later find out, Guillermo is clearly not okay with sharing space with Max, but does so because they have no choice. As the world goes into chaos and nuclear war starts, Varela tells both his own family and Ane’s that he came up with the plan to save Max, but eventually backstabbed him in court. Soon, a war breaks out right outside the bunker that leaves everyone stranded, but as it turns out, it was all a lie orchestrated by Minerva for some reason, and the entire staff is in on it.
Why did Minerva go to these lengths?

It’s shown in episode 3 that Minerva, much like most other people on the planet, wanted to leave behind her poverty-stricken life and live the life of luxury and to do that, she essentially kidnapped a bunch of rich people, hoping to bleed them dry without using any force or guns. She planned out this exorbitant situation and used every means necessary to make the inhabitants of the bunker believe that there was nothing left to go back outside.
The explanation to the madness, however, was simple all along – greed. Minerva wanted a good life for herself and Ziro, one of luxury, and thus, went through all of this work.
Do the residents figure out the truth?
As things start to go from crazy to crazier, Max and Asia start to notice several inconsistencies in the stories that Minerva has been feeding them. That, coupled with the sheer number of guards that are present, leaves Max to wonder why a bunker needs prison-level security. When he finds Yako’s earpiece, he overhears his father’s conversations and realises that they are being monitored. He eventually tells Asia the truth, which leaves them shocked.

Are the residents able to get out?
Although everyone else is more interested in figuring out their personal problems, Max decides to go to the surface, at first, to get medicines for an unwell Mimi. Asia agrees to help her, and he is the only person who is able to get out. Everyone else stays behind, while Mimi dies of a cardiac arrest.
What happens in the end?

Throughout the series, Minerva tries to get Oswaldo to invest in their fake startup to get their hands on Guillermo and Oswald’s money. They go to great lengths to create Guillermo’s clone and figure out his safe password just so that he will go to Bangkok and invest in a sazzy new company that doesn’t exist. Keeping him drugged up and on the brink of sleeplessness, they try to make him mistakenly overlook the inconsistencies in the contract. However, just when he is about to make the transfer, Max and Asia cause another outage that turns the cameras off.
As the money is transferred, the bomb goes off, and Max makes his way out of the bunker. Elsewhere, Oswaldo gets on his plane back home after the deal, but is surprised to see the honeytrap’s picture in one of the advertisements below. He eventually starts to put the pieces together and goes back to Bangkok to find the entire office empty. He eventually figures out that it’s all been a lie, but just as he’s about to report everything to the police, he is killed by Kimera’s goons. At the bunker, Max makes his way out, and the sunlight washes over him.

GARBAGE, sooo BORING, its a big game for rich milionares, and the blew it waaaaay to early in the first episode, the could had built it up slowly, and the prisoners could discovered things as it goes, BUUUT NOT IN THIS ONE,
TOO MUCH ROMANTIC AND TALKING ABOUT FEELINGS…like 70-75% talking…
The bunker itself is very little, not much to see, too little rooms. And not enoug medical equipment…
I don’t like those laughting gruop that doing all that fake acting, and that blonde blond bitch is the most hated person EVER, I DON’T NEED TO HEAR HER STORY ITS PISSING ME OFF MORE…
Too many flashbacks with them planning on have too torture the prisoner…and some are used many times…
PLEASE TELL ME IF THEY MAKE MORE THAT THEY THE CIVILIAN GETS OUT BUT THEY GETS STUCK DOWN THERE AS NEW PRIONSER…FOREVER…
