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?
