This time, the conspirator Belover (Telly Savalas) builds a sanatorium in the Swiss mountains, which is ostensibly an ordinary high-class sanatorium with beautiful scenery and first-class service, but in fact it is an important base for Belofo's plan to control the world. In this sanatorium, Bellover developed a new type of virus, which he tried to inject into the female patients who came here to recuperate, and then spread it around the world through them to achieve the goal of gaining world sovereignty. Belofo's conspiracy attracted the attention of British intelligence, so 007 Bond (George Lazenby) was ordered to dispatch. Bond has infiltrated the sanatorium disguised as a genealogy expert, and he must investigate Belofo's plot in time and stop him!
