The Vault (titled Way Down in various regions) is a 2021 Spanish action thriller film directed by Jaume Balaguer.
Don’t worry it’s in English most of the time with subtitles only when needed.
It stars Freddie Highmore, who fans will recognize from The Good Doctor. He also starred as Norman Bates in the drama-thriller series Bates Motel (2013–2017).
Liam Cunningham, also plays a key role. He is known for playing Davos Seaworth in the HBO epic-fantasy series Game of Thrones.
This is a heist movie. The story revolves around a mission to steal a treasure from the world’s safest vault inside the Bank of Spain. A Marine archaeologist (Cunningham) extracts a treasure from a drowned ship, but the Spanish government seizes it and locks it in a vault inside the Bank of Spain. A team formed by Walter Moreland tries to break into the bank and steal the treasure from the vault.
Thom (Highmore) is the genius engineering graduate who comes on board for the challenge.
From the Cibeles square you can see the Bank of Spain, but more importantly, hiding deep inside is what you cannot see: a vault located 38 meters underground. It’s called the ‘Chamber of Gold,’ a vault containing most of the Spanish gold reserves; ingots and also old coins, like an old coin from the 12th century.
Many security measures protect the chamber, like a 16-ton door; but the most surprising and curious is the security measure related to the most famous fountain in Madrid, La Cibeles. In the event that the alarm goes off, the steel doors will automatically close, the corridors would be sealed off and the whole area would be flooded by the same water feeding the Cibeles fountain, using pipes that lead right to it!
No one has ever tried to break into the chamber (or that’s the official version), but the water is there, waiting for the occasion.
So I don’t believe The Vault is based on a true story, but who knows for sure. The bank would never admit it.
In the film the have a detailed plan to break in, but they only have 105 minutes when the bank’s staff will be distracted, watching the 2010 Football World Cup final match, played by Spain's national football team and broadcast on a giant screen, coincidentally placed just in front of the Bank of Spain building.
