The Star Of Istanbul

the long version

Christopher Marlowe ("Kit") Cobb, an American war correspondent reporting on World War I, has been tasked to follow a man named Brauer, a German intellectual and possible covert SS agent, into perilous waters aboard the ship Lusitania, as the man is believed to hold information vital to the war effort. Aboard the Lusitania on its fateful voyage, Cobb becomes smitten with famed actress Selene Bourgani, who for some reason appears to be working with German Intelligence.
