It is mid-1939 and both Germany and England are preparing for an inevitable conflict. Professor Horatio Smith, an effete academic, asks his students to come with him to the continent to engage in an archaeological dig. When his students discover that the professor is the man responsible for smuggling a number of enemies of the Nazi state out of Germany, they enthusiastically join him in his fight. But things are complicated when one of his students brings a mysterious woman into their circle, a woman who is secretly working for the Gestapo.
