Central City forensic investigator Barry Allen is smart, charming and, as the result of a scientific experiment gone awry, now the fastest man alive. He's The Flash, zigzagging through the action-packed new series based on the supersonic DC Comics character. With his life shadowed by his mother's murder and his father wrongly convicted of the crime, Barry finds that his newfound power of super-speed grants him the ability to move through Central City like an unseen guardian angel.
