At the Bol'Es distillery, Hanna van Bol'Es, her husband Gert, and Paul are hard at work preparing for an important visit from the prince of Macau. Meanwhile, Hanna's sister Claudia gets commended by the mayor for her hard work at Irado, the garbage collection service. When the gift for the prince disappears, tensions rise between the two sisters, leading to an intense feud. Elsewhere, some teenagers - including Hanna and Gert's son Han and Paul's children Lars and Ruud - organize a small party to barbecue and drink exclusive, unreleased "Diamond Gin" by the van Bol'Es distillery. As the night unfolds, hidden emotions surface and the party spirals out of control, until their furious parents arrive to put an end to it. Then, while fulfilling their punishment for underage drinking by working at Irado, Guido and Ronald discover something horrible.
