Hassan and Hussein are ten years old. When they were born they were conjoined twins – this means they shared many organs and had only one leg each. Four months after they were born they had surgery to separate them. They have had many surgeries since then and grow stronger year by year. In this Documentary they are celebrating the 10th anniversary of their separation surgery by setting themselves a big challenge – to climb a huge indoor climbing wall together – all the way to the top! But their plans go wrong when Hassan has a fall and breaks his shoulder.. casting doubt on their big challenge!
