The driver of an army Major knocks down and kills a young boy who looks fourteen years old and wears a Nazi uniform. In the Lab, John shows Hsui Tai a baby rat that is over seven years old - they normally only live to three or four - and explains that he is repeating an experiment the Americans tried, which stopped the aging process before maturity, causing the normal repair processes to work more efficiently, and giving the subject longer life. Tim shows them film of Adolf Hitler inspecting the laboratory of Professor Friedl, who was carrying out the same experiments in the 1940's. Mike arrives wearing parts of an SS uniform, which John tells him in disgust to take off before going out. Meanwhile, in an SS bunker, leader Karl Brandt gives a speech to his cadets in order boost their morale following the escape of one of their number; the cadets have been in the bunker for thirty-three years, since the defeat of Germany at the end of the Second World War. The cadets look after the sleepers, people held in suspended animation. Mike goes to a cafe without his uniform, but three youths wearing SS uniforms and calling themselves �Storm Troopers� attack him for being in their meeting place. Mike returns with a black eye to the Lab, where John tells him that there were gangs of young people all over the world who have developed a fascination for Nazi uniforms. One of the SS cadets finds some fluid leaking from the suspended animation equipment, and the inside person is dead. Tim receives a call on the special telephone line from Major Hughes of the SIS Special Squad, and John sends him a matter transporter to bring him to the Lab. The Major tells them about the boy being killed: German records show that he was born in 1930, and should have been forty-seven, and he also appeared in the film of Hitler Tim showed earlier. In the bunker, Karl decides to wake up Professor Friedl to ask his advice. Mike returns in uniform to the caf�, where the �Storm Troopers� are better disposed to him, telling him that they believe that Hitler is not dead, and will return to lead them. Back at the Lab, John tells Mike that Hitler is actually a shape-changing alien criminal called Neebor, who is on the run from the Galactic Federation. Meanwhile, the SS cadets bring �Hitler� out of suspended animation.
