Film Synopsis

Yves has made up his mind to give up worrying.  He will live each day as it comes, and no longer think about the future.  On his return from Brazil, where he has spent four years, he earns enough to live on by playing his guitar in the streets of Paris.  His home is the Gare de l'Est, which provides him with all the bare essentials - a left-luggage locker for his wardrobe, public toilets for his washroom needs, etc.  However, he hopes to find something better, and to that end he starts to chat up an attractive young woman, Isabelle, hoping that she will allow him to move into her apartment...
