This film is a very well-made war film about an important time in Poland's history--the summer of 1944, when Poland's future after WWII was being forged. By focusing the film on the real life character of a Polish courier, Jan Nowak-Jezioranski, between the Polish Government-in-Exile in London and the Polish Home Army in Warsaw, the film seeks to explain to modern audiences the dilemma the Polish resistance found itlelf in, in the summer of 1944. The Home Army is committed to launching an all-or-nothing uprising against the increasingly nervous German occupiers--The Soviet Army was rapidly approaching, the Western Allies had landed in Normandy, and an attempt had been made on Hitler's life by German officers. The courier is sent to tell the Home Army to cancel the uprising because the Western Allies will not, and will not be able to, militarily support the Home Army, and that the Poland was essentially already promised to the Soviets (there is a little bit of anachronistic revisionism in how exactly this is presented in the film), but in reality, and in the film, it is clear that the Poles would be at the mercy of Stalin given where the front lines were located. Much of the film depicts the travails of the courier getting to Warsaw and meeting the Commander of the Home Army to give him this message. Meanwhile, the Germans, apparently in the form of the SD Security Service, have agents tracking the courier's every move in Britain and are reporting these back to Berlin and/or the German authorities in Warsaw. A female German agent casually returns to Warsaw from London to continue the pursuit of the courier. This part of the film is extremely dubious as neither German military intelligence nor the SD were able to operate effectively in Britain by 1944 In this subplot, the SD follows the courier in Warsaw hoping to locate the Command element of the Home Army so they can negotiate with him a joint defense against the Soviets, allegedly on the instructions of Heinrich Himmler. In some scenes it seems they just want to eliminate the Home Army leadership. Whereas Himmler did seek to negotiate with the Western Allies in the (literally) final days of the war, in mid-1944, this is just silly that Himm;er would negotiate with the Home Army or that they would ever trust him. This unrealistic sub-plot apparently was intended to add excitement to the film. After the courier finally briefs the Home Army Command that the Western Allies will not help, the Home Army decides to launch the uprising anyway to demonstrate for future generations that for a brief moment Poland liberated itself. The whole film seemed to be constructed to lead to this scene, which is correctly focused on the Polish audience. If one is interested in Polish history or in the details of WWII history and politics, this film is well worth watching. If you are looking for a straight forward action movie, you might be disappointed. The actual real-life adventures of Jan Nowak-Jezioranski before and after the period covered in this film are quite interesting and it would have been nice to have a 5 or 10-minute biography of him offered as an "extra" on the disc.
