No way?(Pas cap?)

During the summer, the children of Toulouse in France discover their river almost dry. Eager to grow up in a world where fish will not be roasted by the sun, the children imagine their ideal city, a city that no longer uses fossil fuels. But what would a week without oil look like? Children challenge themselves to do without it, and their families, to their great misfortune, will be associated with it willingly or by force. The consequences will not necessarily be the ones we imagine.
