A referendum plunges Switzerland in a state of emergency. Switzerland shall from now on have only one national language : French. In consequence, many German and Italian-speaking Swiss are in a state of crisis. Among them is fifty-six years old Walter Egli, who works for the federal police and has to ensure that the transition to monolingualism is carried out properly. Although he speaks little French himself, he is sent to Ticino with a French-speaking partner to uncover a Ticino resistance group that is fighting the new law by any means necessary.
