The Flodders are about to inherit a fortune from an old aunt, but only if Ma Flodder displays good manners can she achieve nobility and get the cash.

The queen decides to visit Zonnedael on the national holiday of Queens Day. The neighbourhood as wel as the local government try to get rid of the Flodders for this day so the family can't ruin the festivities. However, the Flodders have no plans on leaving since it's Ma's birthday.
