It is the late summer of 1940, and the Battle of Britain is at its height. Racing for the coast, following a bombing mission over southern England, a straggling He111 of KG55 has been attacked by a Spitfire of RAF Fighter Command. The bomber is badly damaged, but in the nick of time a pair of Me109s of JG26 have come to the rescue, sending the Spitfire diving into the Channel. If they are lucky the Heinkel crew may still make it back to their base in France.
