The fourth season of the hit series Money Heist plunges the Professor’s plan into its most desperate and chaotic phase. Following the shocking cliffhanger of Season 3, the season opens with the gang reeling from Nairobi’s brutal shooting. Trapped inside the Bank of Spain and surrounded by police, the team must navigate a new, more volatile enemy in the form of Inspector Alicia Sierra. With the Professor’s location compromised and his perfect plan in tatters, the mastermind finds his genius truly tested for the first time.
Inside the bank, the heist crew is fractured by grief and rage over Nairobi’s condition. A fierce battle for survival ensues as Gandía, the ruthless head of security, breaks free from his captivity. He wages a one-man war against the robbers, turning the bank’s corridors into a bloody battlefield. This internal threat forces Denver, Stockholm, Manila, and the others into a relentless fight for their lives, pushing their resolve and loyalties to the absolute limit while they struggle to maintain control of the hostages and the gold.
Outside, the Professor faces his greatest crisis as Alicia Sierra closes in on his secret hideout. Captured and interrogated, his meticulous web of lies begins to unravel under her cunning pressure. The season masterfully cross-cuts between the intense action inside the bank and the high-stakes psychological duel between the Professor and Sierra. This cat-and-mouse game challenges the Professor’s intellect like never before, forcing him to rely on his external team, including the newly returned Berlin in flashbacks, to find a way to outsmart his cunning adversary.
Flashbacks provide crucial depth to the current narrative, focusing on Berlin’s past. These sequences detail the elaborate five-month preparation for the Bank of Spain heist, revealing how the Professor recruited Palermo and how the complex relationship between Berlin and Palermo ultimately sowed the seeds for the internal conflicts the gang now faces. These glimpses into the past add emotional weight and explain the present-day tensions threatening to tear the entire operation apart from the inside.
The season builds to an explosive and emotional climax, culminating in a devastating loss for the team. A daring plan involving a military tank and a triumphant, yet short-lived, moment of victory is quickly overshadowed by tragedy. The finale leaves the gang and the audience in a state of shock, setting the stage for a final, vengeful battle. The team, more united by pain than ever, is poised to finish the heist not just for the money, but for honor and revenge.
