Dunkirk

During World War II, a small group of survivors is stranded in a lifeboat together after the ship they were traveling on is destroyed by a German U-boat.

The story of Operation Market Garden—a failed attempt by the allies in the latter stages of WWII to end the war quickly by securing three bridges in Holland allowing access over the Rhine into Germany. A combination of poor allied intelligence and the presence of two crack German panzer divisions meant that the final part of this operation (the bridge in Arnhem over the Rhine) was doomed to failure.

In the summer of 2014, a World War II veteran sneaks out of his care home to attend the 70th anniversary commemoration of the D-Day landings in Normandy.

In the midst of World War II, the battle under the sea rages and the Nazis have the upper hand as the Allies are unable to crack their war codes. However, after a wrecked U-boat sends out an SOS signal, the Allies realise this is their chance to seize the 'enigma coding machine'.
