Katie Tredoux, resident of the retirement village, Stille Waters, finds out that her deceased sister, the infirm Geraldina de Jongh's estate, was unfortunately bankrupt.

She is furious and seeks help from her friends, Greta, Dak and Cyril, co-residents of Huis Stille Waters, to make a plan to keep Geraldina alive. They decide to confront the wealthy businessman Claudius van Straatten (Geraldina's former husband). However, they would never have been able to provide for what great escapades they would end up with.
