The Five Aces - The Judo Master's Secret

Another big day at the sports school. Judo grandmaster Yamada Yuoto has been invited from Japan to spend the week giving presentations and training sessions. Linh in particular is learning much from him. After a competition the friendly and always attentive grandmaster begins to behave oddly. He seems distracted, withdrawn and extremely nervous. Then he disappears without a trace. The five friends begin to investigate and stumble upon the trail of an ancient, rare book that describes various judo death moves. In the course of a risky undercover operation Linh lands in a lot of danger, from which only the grandmaster and her friends can save her.

A genius with any ball, a supple gymnast, an untiring runner, a keen swimmer and an (almost) unbeatable decathlete - they are the 'Five Aces'! Lennart, Michael, Linh, Ilka and Jabali are all close friends as well as being mad about sports. Together the five young sports aces, from five different continents, dive head first into every adventure - and at the same time have a lot of fun in sports.
