2025

A tree made of plastic bricks—it's a good idea, right? Cécile is convinced of it... until Max and Mathieu point out a detail that changes everything: her tree is made of plastic... and plastic comes from oil! But where does oil really come from? How is it turned into plastic? And above all, are there more environmentally friendly alternatives? Curious, Cécile sets out on a mission to trace plastic back to its source: from the earth's subsoil to toys. Meanwhile, Mathieu embarks on another investigation: can plastic be made without oil? And if so, how?
