After three months of training Hanne has passed a first test: she has - successfully - danced a solo on the annual dance performance of the school of her coach Geneviève Van Quaquebeke. But a few days later a setback follows: Hanne has knee pain that does not want to leave. Dr. Lagae, a knee specialist who has already treated a few Red Devils, is formal: Hanne has to be quick under the knife. Her meniscus is torn and that does not heal automatically.
