1940. The Allies are losing the continent.
A Blenheim Wing of Coastal Command stand ready.
The Station Commander is obsessed with a promotion for himself. A promotion that can only be won by the air crews he insanely sacrifices despite heavy casualties.
The Squadron Commander is wracked by the horrors to which he commits his men. His self-confidence is destroyed and he suffers from an erosion of his own mental and physical stamina as he shares their dangers.
The squadron’s pilots, observers and air gunners are weary, dogged and unfailingly brave. They know that an under-strength R.A.F., further depleted daily in battle, is all that stands between Britain and defeat.
They back up Fighter Command by patrolling the Dunkirk beaches, doing a job for which bombers were never intended.
They share Bomber Command’s task of attacking heavily defended land targets.
They strike against enemy ships and hunt U-boats.
