Ned is an eleven-aged boy whose father is a priest. His mother gets serious disease. At his birthday, his uncle gave him an air gun by which he shot one eye of a cat by chance. Although he was deeply afflicted with his guilty, he still had no courage to tell others the truth. Fortunately, his friend, the old Scully was responsible for taking care of this injured cat, thus allowing the one-eyed cat to survive. When Mr. Scully was at his verge of dying, Ned finally got the courage to tell him the truth about the cat. Therefore, Ned knew the cat was still alive, and his guilty mood just relieved as if put down a heavy load. Meanwhile, his mother took a favorable turn from her serious disease, and afterwards Ned regained sunshine in his life.
