Jacques is a soldier who is called away from his military leave in order to take part in a secret mission. It couldn't have come at a worse time, as he was just about to propose to his girlfriend. With considerable cunning and guile, this dull-seeming super-soldier gets the whole operation moved. Now ensconced in her hotel, he can keep an eye on his girlfriend and do his job at the same time.
