Ja Zuster, Nee Zuster

In the guest-house of sister Klivia, the inhabitants are very cheerful and good-hearted persons whose open communal lifestyle is contrasted with the life of somewhat nasty and complaining neighbour Mr Boordevool. Boordevool has spent ages looking for reasons to shut the guest-house. One day a girl from the guest-house meets a nice young guy Gerrit. Sister Klivia lets Gerrit stay regardless of him being a thief. Will that give a chance to the insinuations of the neighbour?
