Grand Slam (1967) Timeline Explained – Every Event in Order

Professor Anders, a mild-mannered American teacher who had spent years lecturing in Rio, grew bored with his life and decided to retire from teaching with one final, ambitious project. Rather than settle into quiet retirement, he chose to orchestrate a major diamond heist during the Rio Carnival, viewing it as the ultimate intellectual challenge.

The team used a pneumatic trestle device that allowed them to crawl over the photocell beams without breaking the light signals. This mechanical solution let them infiltrate the building's protected corridor while remaining undetected by the security sensors.

Agostino Rossi, the Italian mechanical and electronics genius, discovered a clever workaround to circumvent the Grand Slam 70 alarm system one day before the heist. His solution maintained plausible deniability while allowing the team to proceed with opening the safe without triggering the sensitive sound and disturbance detectors.

Foreshadowing: The team initially worried about the new Grand Slam 70 system during planning, setting up Agostino's crucial discovery.

Jean-Paul Audry, the French playboy on the team, was tasked with seducing Mary Ann, the only woman who had a key to the diamond vault. Through manipulation and charm, he gained her trust and obtained the key temporarily, allowing the team to access the building's inner sanctum.

The day after the successful robbery, Mary Ann discovered that her key had been temporarily taken during the infiltration. This realization alerted her that something was wrong, and she notified the authorities, triggering the police pursuit that ultimately doomed the crew.

Foreshadowing: Jean-Paul's key acquisition during the heist planted the seed for Mary Ann's discovery.

During the chaotic escape after the heist, Erich Weiss turned on his teammates and murdered Jean-Paul Audry. This betrayal was driven by greed and paranoia, Erich wanted to keep more of the diamonds for himself rather than share with the rest of the crew, demonstrating the film's theme of loyalty tested by desperation.

The diamonds passed through multiple hands after the robbery. Erich initially had the case but was killed by Milford, who discovered it was empty. Anders and Mary Ann then swapped fake diamonds for real ones in Rome, but two thieves on a motorcycle immediately stole the gems, leaving everyone empty-handed.

The elaborate heist unraveled due to paranoia, betrayal, and greed among the crew members. Erich's murder of Jean-Paul, the police discovery triggered by Mary Ann, and ultimately the motorcycle thieves stealing the diamonds all contributed to the plan's collapse. No one ended up with the prize, reflecting the film's cynical view of criminal ambition.

Gregg Hutchinson, the English safecracker, was killed during the roadblock chase as the team attempted to flee. When police cornered them, Jean-Paul was identified and Gregg was killed in the ensuing pursuit, becoming one of the first casualties of the failed heist.

After the heist fell apart, Agostino Rossi escaped back to Rio to be with his love interest Setuaka. However, upon arriving, he was shot and killed by police bullets, eliminating another team member and sealing the grim fate of the crew.

Milford, Anders' criminal contact who helped assemble the team, intercepted Erich at the designated meeting point. After Erich delivered the diamond case, Milford killed him and discovered the case was empty, the diamonds had already been diverted elsewhere, making Erich's betrayal pointless.

The team moved the heavy safe from its room into the corridor using shaving cream to dampen the sound. This reduced the distance they needed to carry the safe and minimized the risk of triggering the Grand Slam 70 alarm, which was sensitive to sounds and disturbances.
