Question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Ryan's Daughter Movie plot: The film takes place in the isolated village of Killary on the Dingle Peninsula in Ireland during World War I. The villagers are nationalist and exclusionary, taunting Michael (John Mills) (the mute village idiot) and British soldiers stationed at a nearby army base. They are resentful of Rosy Ryan (Sarah Miles), the spoilt daughter of the local publican Tom Ryan (Leo McKern), who himself is an informer for the British army hoping to keep the peace in the village. In public, Ryan pretends to be a staunch nationalist; in an early scene, he strongly supports the recently suppressed Easter Rising, referring to the rebels as "our boys".Rosy is bored with her humdrum village life and fantasizes about the outside world much to the chagrin of the local priest, Father Hugh Collins (Trevor Howard), an old, sharp-witted and highly influential person who knows all that goes on in the village. Rosy is in love with the local schoolmaster, Charles Shaughnessy (Robert Mitchum), a widower older than herself. She imagines that Shaughnessy will be able to add excitement to her life because he is educated and listens to classical music. He tries to convince her they are not a good match and suggests she leave the village and see the world. The two ultimately marry, but Rosy quickly becomes discontented with her marriage. She is looking for passion beyond just love in her relationship.Major Randolph Doryan (Christopher Jones) arrives to take command of the local army base. A veteran of World War I, he has been awarded a Victoria Cross, but has a crippled leg and suffers from shell shock. Rosy is instantly attracted to him. When Michael absent-mindedly bangs his foot on the pub bench, it causes Doryan to have a flashback to the trenches and collapse. When he recovers, he is comforted by Rosy. The two passionately kiss until they are interrupted by the arrival of Ryan and the townspeople. The two arrange to meet the next day horseriding and end up in the forest for a lengthy liaison.Charles becomes suspicious of Rosy, but keeps... My question: What haunts Doryan?
Answer:
He suffers PTSD from his time in the trenches in World War I
