Gaston is a new guy at the Peticoin start-up. With his delusional inventions, he will change the lives of his colleagues. Cat, seagull, cow, and gaffophone will be at the center of the mishaps of this genius laidback handyman who wants only to do good, but has the gift of annoying Prunelle, his boss. Can those Gaston’s gaffes galore prevent the buy-out of the Peticoin by Mr. de Mesmaeker?

Arnaud, facing an uncertain future and a dearth of choices in a small French coastal town, meets and falls for the apocalyptic-minded Madeleine, who joins an army boot camp to learn military and survival skills to prepare for the upcoming environmental collapse. Intrigued and excited by Madeleine’s wild ideas, Arnaud signs up for the boot camp himself. They soon realize that the boot camp is harder than they’d imagined, but the experience nonetheless cements them together as the couple continues to explore their young love.
