As a psychiatrist at a respected Scottish asylum, Dr. Rivers heals shellshocked soldiers so they can be sent back into the trenches. Then he encounters a different kind of patient - a war hero sent to the asylum for publishing an outspoken anti-war pamphlet. As each struggles to cope with the war, the line between patient and doctor begins to blur. Taken from Pat Barker's 1991 novel Regeneration and based on true events.
