Carry On Spying

The chief of the Secret Service reluctantly entrusts Desmond Simpkins with the mission to recover the stolen top-secret chemical formula. He is accompanied by three trainees: Harold Crump, Daphne Honeybutt, and Charlie Bind. The agents are dispatched to track down STENCH and the missing formula, despite their evident ineptitude. The goal is clear: retrieve the formula before STENCH uses it.

The agents travel separately to Vienna where each makes contact with Carstairs, who assumes a different disguise for each rendezvous. Carstairs acts as their primary go-between and guide in the web of disguises and misinformation. The meeting sets up the next moves in their chase for the formula.

The group converges at Cafe Mozart in Vienna where Carstairs’ disguises reveal himself and provide crucial intel. Tensions run high as they piece together how the STENCH plan operates. The Cafe serves as a nerve center before they head toward Algiers.

From Vienna, the agents continue to Algiers to pursue the stolen formula and cut off STENCH’s grip on the deadly plan. They must navigate a gauntlet of distractions and potential double agents along the way. The risk of interception by STENCH increases as they close in.

During the journey, STENCH operatives the Fat Man and Milchmann—disguised as a milkman—seize the formula. The act demonstrates STENCH's reach and the vulnerability of the team. The theft forces a drastic change in their plan as they race to recover it.

The agents’ bungling leads to Carstairs being floored in an encounter with the Fat Man. The setback leaves the remaining agents scrambling to salvage the mission and protect the vital intelligence. Their failure to protect Carstairs raises the stakes for every following move.

Daphne and Harold disguise themselves as dancing girls in Hakim's Fun House to steal back the formula while the Fat Man is nearby. They also encounter the enigmatic Lila and must decide whether she can be trusted. Daphne memorizes the formula with her photographic memory and the group contemplates destroying the papers.

The four encounter the mysterious Lila, a figure whose loyalties are unclear. They are uncertain whether to trust her, but she becomes a pivotal ally as the chase continues. Her presence adds tension and a possible double-cross to the mission.

With a photographic memory, Daphne memorizes the entire formula, ensuring it can be recalled even if the papers are destroyed. The team weighs the risk of keeping the information hidden versus risking capture. This memory becomes the key to their potential success or failure.

The team ends up captive in STENCH's base where Daphne is interrogated by the evil Dr Crow. She resists breaking, but a bump on the head accidentally forces her to reveal the formula. The leak sparks a desperate effort to salvage what she disclosed.

Simpkins, Crump, and Bind manage to escape their cell and recover Daphne and Dr Crow’s tape recording of Daphne’s recitation. They are swept into an underground automated factory process and must flee through a hazardous system. Lila intervenes, pulling a gun on Dr Crow to force a reversal of the process.

Simpkins initiates the self-destruct sequence for the STENCH base and rushes into a lift with the others, including Lila and Dr Crow. As the ascent begins, Lila reveals she is a double agent for SNOG and confesses a crush on Simpkins. The team races toward the surface as chaos erupts behind them.

The lift reaches the surface, revealing the chief’s office as the Secret Service headquarters. The STENCH HQ lies just below the streets of London and detonates in a smoky explosion, choking the chief’s office and ending STENCH’s threat for now. The mission culminates with the rescue of the team and a precarious victory.
