In 2017, a cryptic figure known only as The Professor masterminds the most ambitious heist in recorded history: the Royal Mint of Spain. He assembles a team of eight highly skilled, yet emotionally scarred, individuals, each codenamed after a city, to execute a plan that is as much about rebellion as it is about money. Led by the charismatic and impulsive Tokyo, the team takes 67 hostages with the intention of printing billions of euros and escaping undetected. However, their meticulous plan is immediately tested by the arrival of the brilliant and relentless police inspector Raquel Murillo, who engages in a high-stakes game of psychological cat-and-mouse with The Professor from outside the Mint's walls. Inside, the tension is palpable as the team navigates internal conflicts, personal vendettas, and the constant threat of the armed forces storming their fortress. A stylish, high-octane thriller, the series weaves together a complex narrative of loyalty, love, and sacrifice, proving that in this game, the true battle is not just for money, but for the very soul of the team.
