But Hedvig is not a superhero, and the challenges are far greater than her coaching father anticipated. He soon realizes focus must shift to his athletic nephew Adrian instead. Dejected and confused, Hedvig visits her demented grandmother. As she starts talking about the situation, the grandmother lights up, eagerly responding to her ramblings. An unlikely team emerges, and soon Hedvig is about to fulfil their family legacy without her father’s knowledge.
