Checkpoint 1957

O’Donovan breaks into a safe in a factory in Florence, Italy, late at night. That triggers a burglar alarm, and he shoots the night watchman and at least one policeman; his gunfire also starts a fire that consumes the factory. He goes to Francesca and demands she put him in contact with Petersen, her boss. Petersen hides O’Donovan at his villa.

In England, Ingram tells Michael of his connection to the fiasco. Ingram, an industrial magnate, hired O’Donovan to lure away the designer for the Volta D’Italia car racing team, in hopes of making his team world champions. O’Donovan was unable to do that, so turned to industrial espionage, against Ingram’s explicit orders not to do anything illegal, violent or risky. Ingram decides to smuggle O’Donovan out of the country, and Michael recommends driver Bill Fraser who needs money for a race car he has designed and is building.

The team board a flight to Italy, followed by Ingram and Michael. There, Fraser mends his strained romantic relationship with Francesca. Hiding at Petersen’s villa, O’Donovan is displeased to hear that Ingram wants him to go to Bombay via Switzerland. O’Donovan tells Petersen to inform Ingram that he will sell the plans for the “fuel intake” Ingram wanted. At his team’s garage, Ingram tells team manager Thornhill to team young driver Johnny Carpenter with his friend Fraser for the important upcoming race from Florence to Locarno. After sending Thornhill to the refueling stop at Milan, Ingram meets with O’Donovan and reluctantly buys the plans.

Between them, Petersen and his girlfriend Gabriela drug Johnny’s drinks. Next day, Ingram calls Bill to Johnny’s room, where Johnny is unconscious next to a whisky bottle. Since no last-minute driver changes are allowed, Ingram offers Bill financial backing for his race car in exchange for taking the risk of breaching the rules by substituting another co-driver for Johnny. Bill agrees.

On the day of the race, Francesca goes to Johnny’s room to fetch him, but runs into O’Donovan and Petersen. Petersen holds Francesca captive while O’Donovan masquerades as Johnny. Ingram tells Francesca that if she notifies the authorities, Bill will go to prison. She is then released, though Ingram orders Petersen to follow her. She books a flight to Milan and breaks away from Petersen and gets aboard.

At the race-stop in Milan, Francesca warns Bill, but O’Donovan points his pistol at him, so Bill resumes the race. Francesca asks for Thornhill’s help, and he drives her on a shortcut across the mountains to intercept Bill and O’Donovan without involving the police. Bill pulls over, complaining of a loose wheel or flat, and tries to overpower O’Donovan, but fails. O’Donovan orders Bill not to stop at the last checkpoint, even if they need to refuel to reach the finish line. Fearing for his life, Bill ignores O’Donovan’s order to slow down, since O’Donovan cannot safely shoot him without endangering himself. Bill then deliberately takes a wrong turn, heading back from Switzerland towards Italy. Once O’Donovan realises what Bill is doing, he tries to grab the wheel. The car goes off the road and teeters on the edge of a cliff. The two men get out and fight, as Ingram, Francesca and the others converge on the scene. O’Donovan is knocked into the car, which then plunges over the cliff and into the lake. Ingram, struck by falling debris, makes a full confession to a frontier guard, taking full responsibility.
