Sam Dance is a young enlisted soldier in 1941 when his older brother Keenan is killed at Pearl Harbor. Afterwards, Sam promises that he will do anything he can to stop the war.
During his training, Sam begins to show that heÂ has a knack for science and engineering, and heÂ is plucked from the daily grunt work of twenty-mile marches by his superiors to study subjects like code breaking, electronics, and physics in particular,Â a science that is growing moreÂ important to the war effort.Â While studying, Sam isÂ seduced by a mysterious female physicist that is teaching one of his courses, and given her plans for a device that will end the war, perhaps even endÂ the human predilection for war forever.Â ButÂ the deviceÂ does something less, and more, than that.
After his training,Â Sam is sent throughout Europe toÂ solve both theoreticalÂ and practical problems for the Allies.Â He spends hisÂ free timeÂ playing jazz, and trying to construct the strange device. It's only much later thatÂ he discoversÂ that it worked, but in a way that he could have never imagined.
