An excellent tale of the "Few" and the Battle of Britain. T.B. Baird (John Gregson) - who gets the nickname Septic due to his unfortunate initials - turns up at a Hurricane squadron. Though he doesn't get off to a good start with his CO "Tiger" Small (Jack Hawkins) and Squadron Leader Moon (Michael Denison) - who is rare in not having a nickname - when he crashes his plane on arrival!
After a period of being given ground duties he finally gets airborne during an emergency and gets his first kill but still gets a bollocking after leaving his radio channel open. However, he is soon a regular in the air and proving his worth but as the Luftwaffe steps up it's attacks the squadron is pushed to the brink both in the air and on the ground.
The film doesn't include a lot of flying scenes it concentrates more on the humans than the machines. The emotions, the fears, the camaraderie and often the ridiculousness of war and young men being sent to their possible deaths time and time again.
