You will find yourself plunged into the depth of winter in 1916, through the love letters of a soldier and his fiancée. It is Christmas Eve, in a snow-covered trench, where smoke invades the tunnels, the ground shudders with each new explosion, and the sirens wail…..All seems lost, but on this 24th December, the soldiers do not yet know that they are going to live a Christmas they will never forget!
