Sammi has his first day of work as a prison guard in a large, old prison called Huset. The seasoned officer Henrik explains that the strong inmates drive the weak in prison - and that's a good thing, because it gives good peace and order. However, the prison officers receive a shocking message - the shot must be reversed, and they have three months to do so, otherwise the prison risks closing. From now on, it is zero tolerance, the strong prisoners must have less power, and hashish sales, steroids and loan shops must be a thing of the past.
