Ryan’s mum is a taekwondo champion and Ryan’s hero. With another championship almost in the bag, her arm suddenly stops moving during the final bout, and she is defeated. The doctor diagnoses multiple sclerosis, but Ryan doesn’t really understand what is going on, or how he can help. Luckily, the Medikidz are on hand to take Ryan on a trip to Mediland where they see up close what happens to the body in MS.
