For more than 100 years, the adults in Valsjöbyn in Jämtland have been playing "Gyminga" on the eve of Ascension Day. The boys in the village gather at the store to draw up the strategy.
They should hide "within four walls and ceilings" and everyone should hide in the same place. When time starts to run out, Daniel Fahlström is not as sure anymore and when the clock strikes 21.00 he and the other boys are forced to give up.
