On the way to the ruins of St Helena, once an island prison for men off the Queensland coast, Sally Cooper browses through a booklet on the island's dark history. A story on William O'Meally, sentenced to life imprisonment for manslaughter, captures Sally's interest. As she reads of his several escape attempts and of his suicide by hanging, Sally finds herself strangely affected by his photograph; his hypnotic eyes are filled with intense desperation. Haunted by William's plea of innocence, Sally's past and present are about to fuse.
