One of Our Spies Is Missing (1966)

In the heart of England, the enigmatic Ilya tracks a peculiar man with an obsession for cats, only to find himself injured in the pursuit. Across the pond in New York, his colleague, the suave Napoleon Solo, is tasked with a curious case by Waverly: the vanishing of a renowned scientist, replaced by a man bearing an uncanny resemblance to a younger version of the missing expert. His pursuit leads him to the scientist's model daughter in Paris and a cryptic encounter with a man engaged in conversation with an aging politician, whose wife is the employer of the scientist's daughter. A sudden act of violence sends Solo on a wild chase, but the shooter eludes him. His next stop is a meeting with the secretive fashion designer, the politician's wife, but his path is fraught with danger as his car is sabotaged. As the threads of the mystery intertwine, Solo finds himself aligning with Ilya, suspecting a common link between their respective assignments. Meanwhile, a sinister experiment involving cats is underway that could potentially reverse the aging process. The missing scientist, Dr. Lancer, resurfaces looking miraculously younger, sparking speculations of his involvement in the ominous project. The world of high fashion becomes the backdrop of a grand conspiracy as Solo and Ilya uncover a plot devised by influential women of the industry to exploit the anti-aging machine for their personal use. However, the plot thickens when the suave THRUSH agent, Jordin, enters the scene with his own devious agenda. A thrilling race against time ensues as UNCLE and THRUSH vie for control of the groundbreaking machine, with the fate of the missing scientist and the world hanging in the balance.
