idea for childrens film

We are going to do a film about a young racer who loses his arm in a crash and now is a disabled child who aspires to be the greatest race driver that ever lived. David and Gary attended the local race day where David stumbled across a great idea to be the greatest. As the race is over, David begins to realise that his dream is possible, and with the help of his friend Gary, he works hard to practice and achieve his goal. Also, in the crowd next to him, Lewis Hamilton overheard his dreams and decided to help David achieve his lifelong dream. However, in a horrific accident David loses his left arm and is out of action for a couple of weeks. The film will be called SPEEDY DAVE.
