This gripping, stranger-than-fiction espionage thriller brings to life the incredible true story of Moe Berg, the professional baseball player who became a World War II spy. A Jewish, Princeton-educated, multilingual catcher for the Boston Red Sox with a closely-guarded private life, the enigmatic Berg (Paul Rudd) was already a man of mystery when, in 1944, the US government's wartime intelligence agency enlisted his services. His mission: go behind enemy lines in Europe to assassinate the Nazi's chief nuclear scientist before the Germans develop an atomic bomb. Trading in his catcher's mitt for a trench coat, Berg must rely on his formidable, steel-trap intellect in a high-stakes game of cat and mouse-with the fate of the world hanging in the balance. Jeff Daniels, Paul Giamatti, and Sienna Miller costar in this remarkable slice of forgotten history.
