Michael has been told to never stare at his grandfather when he comes for rare visits. During World War II, Grandpa served on a British merchant vessel that was torpedoed and engulfed in flames, leaving his face a grotesque mask. When Michael turns 12, he starts spending summers with Grandpa, fishing off the Isles of Scilly. It is only when Michael is older, a high school graduate, that the grandfather recounts what happened in all its horrific detail.
