Output: Mr. Sebastian is a former Oxford professor, who in the late 60s directs the allfemale decoding office of British Intelligence. One day, while running through the streets of Oxford to attend the bestowing of an honorary degree on his friend the Prime Minister, Sebastian runs into Rebecca Becky Howard and her jeep. After insulting Sebastian on the spot, Becky is intrigued by him and follows him to the ceremony. After Becky is able to spell her own name backwards, he gives her a phone number to call if she wants an unspecified job. Becky calls the number, and after Sebastians personal assistant Miss Elliott describes the job as being part of the civil service, Becky is turned off by the idea. Overcoming her concerns, she calls again, and after a successful interview, obtains a job deciphering codes used by secret agents and foreign spies. Once settled in her new job, Becky slowly starts to fall for the aloof Mr Sebastian. However, problems arise when Gen. John Phillips, Head of Security, accuses Sebastians senior Jewish decoder Elsa Shahn of being a poor security risk, because of her leftwing Communist leanings. Sebastian convinces the Head of Intelligence to retain Shahn despite Phillips objections, expressing how vital Shahn is to the decoding office and reaffirming that she enjoys his full confidence. Eventually, Becky and Sebastian engage in an affair, which upsets Sebastians longtime girlfriend and washedup pop singer Carol Fancy. Ultimately, Shahn betrays Sebastians trust by providing recently decoded information to a leftwing political organisation. When confronted with the security breach by the Head of Intelligence and by Phillips watchdog Jameson, Sebastian tenders his resignation and breaks up with Becky, thinking she was on to him. He leaves London and returns to his teaching position at Oxford University. Months later, Sebastian is visited at Oxford by the Head of Intelligence, who convinces Sebastian to return, temporarily, to the decoding office to help the Americans decipher some unidentified signals emanating from a Sputniktype Russian spy satellite circling the earth. To prepare for this assignment, Sebastian visits a secret British eavesdropping installation, where he meets the American Ackerman Donald Sutherland, who is working on the project. One day, while looking for Becky, who has also left the decoding department after Sebastians resignation and breakup, Sebastian runs into Carol, who invites him to a party at her apartment for old times sake. At the party, Sebastian is drugged with LSD and lured to the top of the building by Toby, who unknown to Sebastian, is both Carols lover and a foreign agent. Just as the hallucinating Sebastian is about to jump off the building ledge to his death at Tobys insistence, he is saved by Gen. Phillips, who had been tailing both men, and Toby is arrested. Sebastian returns to the decoding office, and finds out where Becky lives. While visiting Becky, Sebastian discovers that he is the father of her newborn baby. During this visit, a noise from the babys rattle provides Sebastian with the solution to the Soviet spy satellites signals, which he eventually breaks with the help of his faithful group of decoding girls, who are summoned to Beckys apartment to decipher the Soviet code.
