"The Origin of Daredevil"
Meet Matthew Murdock, an 8-year-old living with his widowed father, washed-out boxer 'Battling' Jack Murdock. Matt is a brilliant student, and keeps himself fit. Tragedy strikes as Matt saves an old man from being run down by a truck delivering radioactive chemicals. The truck crashes, spilling waste over Matt's eyes. He is blinded, but his other senses are mysteriously heightened. As he grows to a young adult, he adapts to his powers and takes on the persona of Daredevil, and begins a career in a law office with Foggy Nelson. Meanwhile, Battling Murdock wants to make his son proud, and wins a fight that organized crime boss, the Fixer, had demanded he throw. The Fixer has Matt's father killed. Daredevil crushes the Fixer's operation. 23 pages.
