A former Nazi, now living in the 1990s by virtue of anti-aging pills, plans to travel through time to 1944 Germany and present Hitler with a hydrogen bomb so the Nazis can win the war. He teams up with a conniving man who has taken over the life of his brother, who choked to death on a roll. Things go awry though and the time travelers land in the wrong year and find themselves at odds with the Nazis. Their pilot plots to return one day before they left, thus foiling the Nazi plot altogether.
