Carmen's foppish tendency to buy things needlessly, often useless junk, breaks the Waterslaghers family finances and drives whipped husband Xavier to uncharacteristic measures. Beacuse Marc's rich ma keeps showering baby Pauline with gifts, Bieke's less affluent ma feels she must follow to prove equal love. Bieke tries to forbid both to bury their tiny home under presents, but the kid's birthday is coming up, and neither grandpa manages to control his wife any better then Xavier his.
