Some Girls Do (1969) Timeline Explained – Every Event in Order

Carl Petersen is sabotaging the SST1 supersonic airliner project to profit financially. He stands to gain eight million pounds if the aircraft fails to meet its crucial deadline. The film presents him as a criminal genius who has devised an elaborate scheme involving robotic agents to ensure the project's failure, making his eight-million-pound payout guaranteed if the airliner never completes its maiden flight.

Foreshadowing: Petersen's financial motive is hinted at early when the accidents begin occurring specifically around critical testing phases.

Infrasound technology in the film refers to sound waves below the threshold of human hearing that can cause severe damage when directed at people or machinery. Petersen's robots use this technology to sabotage the SST1 project by producing harmful sound waves that can affect both human targets and aircraft systems. The devices are small enough to be concealed and include a miniature version used in the powerboat confrontation.

Foreshadowing: The mysterious accidents affecting both people and machinery early on hint at some form of invisible technological weapon.

Flicky escapes on the powerboat with the infrasound device, revealing herself to be a double agent working for the Russians. After Drummond thwarts Petersen's plan, she takes the device and leaves Peregrine behind. Peregrine actually chooses to go with her to foster better relations with Russia, implying he too may have secret allegiances despite appearing as a British embassy contact.

Foreshadowing: Flicky's initial characterization as a seemingly naive American conceals her true intelligence operative background, foreshadowing her later revelation as a double agent.

No. 7 is not actually a robot. While she appears to be one of Petersen's female robot workers on his island, she malfunctions and shows genuine human emotions. When Drummond is cornered by her, she chooses not to betray him to the other robots, implying she has free will and genuine feelings. At the end, she and Drummond share a tender moment as the island explodes, with Drummond finding comfort in her company.

Foreshadowing: No. 7 is introduced as a malfunctioning robot whose erratic behavior hints she may not be entirely artificial.

Drummond survives Helga's glider attack through quick thinking and physical skill. After Helga sabotages his parachute ripcord, Drummond manually opens his parachute by reaching up and pulling the cord himself, rather than relying on the malfunctioning automatic release. This allows him to escape the crash that Helga intended to be fatal.

Foreshadowing: Helga's earlier attempt to kill Drummond with a bomb in his telephone establishes her as a direct threat attempting to eliminate him.

Flicky was never truly aligned with Drummond's mission. She is revealed to be a double agent working for the Russians, having infiltrated Petersen's organization from the beginning. During the island confrontation, she helps Drummond initially but then attempts to escape with the infrasound device, revealing her true loyalties lie with Russian intelligence rather than the British or American operatives.

Foreshadowing: Flicky's supposedly scatterbrained demeanor masks her intelligence operative training, which becomes suspicious given her access to sensitive information.

Helga and Pandora, Petersen's female robots, systematically eliminate key individuals involved with the SST1 project. They murder engineer Dudley Mortimer and the secret agent Miss Mary (who ran a cooking class as an espionage cover). The robots carry out these kills as part of Petersen's broader sabotage scheme to ensure the supersonic airliner never completes its flight.

Foreshadowing: The film opens with violent incidents, including a homicidal air stewardess attack, establishing the deadly nature of Petersen's robotic operatives.

Drummond defeats Petersen by using the villain's own infrasound technology against him. After being cornered on the island, Drummond scales the enemy's fortress and reaches Petersen's control room. He redirects the infrasound waves back at the control equipment, destroying the room and presumably killing Petersen, Pandora, and Helga in the explosion. This thwarts the planned destruction of the SST1 during its maiden flight.

Foreshadowing: Drummond's investigation throughout the film has been building toward understanding and countering the infrasound technology.

Peregrine Carruthers chooses to leave with Flicky when she escapes with the infrasound device. He explains that he is going with her to foster better relations with Russia, suggesting he may actually be a Russian sympathizer or double agent himself, despite being introduced as a contact at the British Embassy. This ending implies the British operative had hidden allegiances all along.

Foreshadowing: Peregrine's willingness to work with Flicky despite her suspicious behavior hints at possible ulterior motives.

Petersen's female robots are attractive women equipped with electronic brains, created to carry out his sabotage operations. The main robots are Helga, Pandora, and No. 7. Helga is shown as both alluring and dangerous, carrying out missions including attempted assassinations of Drummond. Pandora is depicted as more lethal and intelligent. No. 7 appears malfunctioning and ultimately proves to be human, not robotic. These robots use infrasound technology to sabotage the SST1 project.

Foreshadowing: The early sabotage by two women during crucial testing phases introduces the pattern of female operatives working against the project.

Helga seduces Drummond as part of her mission to get close to him and eliminate him. At the shooting party, she sleeps with him before planting a bomb in his telephone to kill him. Later on Petersen's island, she seduces him again during dinner, likely as part of surveillance and manipulation. Despite being a robot, she is programmed to use her attractiveness as a weapon, though she develops some form of emotional connection to Drummond.

Foreshadowing: Helga's dual role as seductress and assassin is established from her first appearance.
