Asterix and the Roman Agent

Julius Caesar tries to conquer the little Gaulish village by sending Tortuous Convolvulus to stir up trouble. He succeeds in making everyone (including the Roman garrison) suspicious of everyone else, but Asterix, Obelix, and Getafix see through his scheme. By threatening to withhold magic potion they reunite the confused Gauls, who trounce the equally confused Romans. The only thing everyone understands is that Tortuous Convolvulus is at the root of the trouble, so they ship him back to Rome in chains.
