When their parents decide to raise trout on the roof, the children are up in arms! The fish have to be saved from a sad fate!

A shared roof garden and organic food on every floor: welcome to the greenest building in Greater Paris! At 7 Green Street, there's a lot going on... The parents never stop exploiting their offspring! They make all the decisions between adults and only entrust the children with the chores, like fertilizing and weeding the community garden. And now they've decided to start rearing fish. Exploiting poor animals? Armand and his gang—Lily, Oscar, and his little brother Charlie—are outraged. Fed up with being chopped liver, the children cry out: no more slavery! The hour of their vengeance is at hand... and they're not short on crazy ideas!
