One of Our Spies Is Missing

Napoleon Solo and Illya Kuryakin investigate the theft of cats in London and soon discover that the 83-year-old biologist Benjamin Lancer has been de-aged to a youthful appearance through a mysterious process developed by Dr. Alexander Gritsky and Madame Raine De Sala. As they dig deeper, they uncover a plot by THRUSH to use the rejuvenation process for their own gain, putting Solo's father at risk of being taken over by THRUSH's plans. The U.N.C.L.E. agents must outsmart Olga and Jordin, and eventually team up with Sir Norman Swickert, who has been de-aged and now holds significant power, to prevent the technology from falling into the wrong hands.
