It is 1916.

Private Sean O’Shea (19 yrs old), fighting in Northern France with the Irish Regiment, gradually becomes weaker with mild fevers and night-time sweats, although with so much mud, disease and tiredness in the trenches little notice is taken by the Sergeant Major and Sean struggles on.

He is able to persuade the Sergeant Major to refer him to the Medical Officer who is unsure of Sean’s condition.
