Kees Flodder Jr. thinks Uncle Henk is her biological father. Meanwhile, JP and Menno hold Grandma Flodder hostage for ransom, while Donnie, Paultje, and Priscilla dig up dead pets in Eyckendael in search of golden collars.

Eyckendael's benefit match turns into a battle: Kees Junior starts a campaign to keep her mother, Charlotte enlists Paultje Flodder for her project, and JP wants to reclaim the Flodder House by defeating Donnie with oysters.

Kees Flodder Junior inherits a cellar full of millionaire's seed and gives it away for free, much to the neighborhood's displeasure. When Donnie orders hand grenades, Charlotte intervenes and calls the police, leading to an explosive ending.
