A Lamborghini Miura dramatically navigates the breathtaking scenery of the Italian Alps before meeting a catastrophic fate as it plunges into a tunnel, leading to a spectacular explosion. The aftermath of this incident sees a bulldozer tasked with extricating the wreckage from the tunnel, subsequently unceremoniously dumping the remnants into a steep alpine gorge. Time passes, and we are introduced to the suave mobster Charlie Croker, played by the illustrious Michael Caine, who is recently released from prison.
Soon, he encounters the widow of his fallen comrade and fellow thief, Roger Beckermann, portrayed by Rossano Brazzi. This widow hands Croker the meticulously crafted plans for a grand heist, originally intended to rob the payroll of the prestigious Fiat automaker. This scheme had caught the attention of the Italian Mafia due to its audaciousness and potential profit. Undeterred by the obvious dangers, Croker opts to pursue the robbery, but he quickly realizes he needs a formidable and well-equipped gang to execute such a risky endeavor.
In a bold move, Croker infiltrates the prison to confer with Mr. Bridger, a cunning criminal mastermind who operates his empire from behind bars, brilliantly portrayed by Noel Coward. He carefully lays out the details of "the Italian Job." However, Bridger initially scoffs at the audacious scheme and orders Croker to be punished for disturbing his peace. Yet Bridger’s perspective shifts dramatically when he learns that China is sending a shipment of gold to Turin as a down payment to Fiat for a new factory. This twist of fate provides the perfect impetus for Croker to rally his troops, which include the savvy computer specialist Professor Peach, played by Benny Hill, and the electronics aficionado Birkinshaw, portrayed by Fred Emney.
With a masterful plan in hand, the crew intends to disable Turin's sophisticated computerized traffic control system, inciting a massive traffic gridlock—an ingenious move that would thwart any police efforts to thwart their escape. A trio of nimble Mini Cooper Ss is selected for their ability to weave through the chaos and follow Beckermann's escape route to liberate the gold.
After meticulous planning and rigorous training, Croker and his motley ensemble venture into Turin. Their operation is met with a menacing challenge as the mafia kingpin Altabani, portrayed by Raf Vallone, lays in wait at an alpine pass, prompting a clash that results in the destruction of their Jaguar E-Types and their Aston Martin DB4 being carelessly flung into the gorge. Yet, Croker, with his unparalleled charisma, manages to negotiate an escape from what could have been a fatal encounter by leveraging the threat of repercussions to the Italian community in Britain.
With the gang reinstated, Peach (Benny Hill) uploads his guerrilla software into the traffic control system during the night leading up to the heist. On the fateful day, Birkinshaw artfully sabotages the closed-circuit television, just as Peach's plan catalyzes a cacophony of honking horns, rendering the city immobile. The gang swiftly converges upon the gold convoy, swiftly overpowering the guards and securing the armored vehicle inside the grand Museo Egizio.
As they transfer the precious gold into their Minis, mafioso Altabani realizes the depth of Croker’s cleverness: “If they planned this [traffic] jam, then they must have planned a way out of it.” With adrenaline coursing through their veins, the three Mini Coopers navigate through the bustling shopping streets of the Via Roma, ascend the futuristic sail-like roof of the Palazzo a Vela, race around the Fiat Lingotto factory's innovative rooftop test track, and evade capture amidst the chaos of a wedding at the Gran Madre di Dio church.
In a deleted scene that showcases their lucky escape, the gang narrowly dodges capture at a local school where a band is enthusiastically playing the Blue Danube. They cleverly evade the police by plunging through large sewer pipes, leading to a dramatic conclusion as they make their escape on a uniquely modified six-wheeled Harrington Legionnaire-bodied Bedford VAL coach. Here, they perform a daring maneuver—loading the Minis onto the moving coach.
As once the gold is emptied safely away from prying eyes, the gang regroups with the rest of their crew, who disguised as raucous football fans, managed to slip out of the city in a nondescript minivan. The exhilaration of their feat leads to an uproarious celebration as they traverse a winding mountain road headed for Switzerland, beer flowing freely in their midst. However, an unexpected skid from driver Big William sends the coach dangerously close to the edge of a cliff, creating a nail-biting scenario where the precious gold teeters perilously near the rear doors.
Amidst this gripping tension, Croker's final bid for survival delivers a memorable line: "Hang on a minute, lads, I've got a great idea! Err..." Here, the camera pulls back to reveal the nerve-wracking scene of the bus still precariously hanging over the cliff, leaving the audience breathless and uncertain about the outcome as the credits roll.
