The Adventurers arrive in Paris. It is the year 1844 and they meet a young blind girl called Simone and her teacher Louis Braille. The Hacker's Agents are trying to sabotage Braille and his new system of writing for the visually impaired. The school's insensitive director strongly disapproves of teaching the handicapped, but fighting against the odds the four friends arrive just in time to foil the Agents' plan, allowing the presentation of the brilliant system to take place and teach the director a lesson.
