Koen Kampioen in the lead role is already the eighth part in the 9+ series about Koen van Loon. The Stark team is invited by their old goalkeeper Dennis for a practice match in England. Unfortunately, their trainer throws a spanner in the works. Koen is therefore indignant when it turns out that there is another trip planned... Renske and Aukje are busy setting up their new vlog in the meantime. They would prefer to follow Koen all day long, but Koen has other things on his mind. Why has Niels been so indifferent lately? And how can he manage to see Dennis again? His trainer also thinks the level of the team has been very disappointing lately. How will that be against three top international teams?
