At 11, Barry Allen's life changed completely when his mother died in a freak accident and his innocent father was convicted of her murder. Orphaned Barry later becomes the step-son of Detective Joe West. Now a crime-scene investigator, his dedication to learn the truth about his mother's death drives him to follow up on every new scientific advancement and urban legend. When his latest obsession - a particle accelerator heralded as a world-changing invention - causes an explosion, it creates a freak storm and Barry is struck by lightning. He awakes from a coma nine months later with the power of superspeed.
