The plot is inspired by the British War Department’s declassified documents which contained information about a secret group of military officials formed by the Winston Churchill (L-R: Hero Fiennes Tiffin, Babs Olusanmokun and Alan Ritchson)

A synopsis reads: ‘The top-secret combat unit, composed of a motley crew of rogues and mavericks, goes on a daring mission against the Nazis using entirely unconventional and utterly “ungentlemanly” fighting techniques.

‘Ultimately their audacious approach changed the course of the war and laid the foundation for the British SAS and modern Black Ops warfare.’

As the trailer opens, Henry’s character Gus is heard saying: ‘We both know I’m not very popular with the administration.

‘If I am to do this I’ll need my own team. You won’t like them, they’re all mad.’

Cary Elwes’ character tells him: ‘They’ll need to be.’

As the unit is seen unleashing terror its enemy, Gus is heard saying: ‘This is an unsanctioned, unauthorised mission.

‘If we fail, England will be condemned to a lifetime under the German boot.

The film stars the likes of Eiza Gonzalez, Alex Pettyfer, Henry Golding and Babs Olusanmokun.
