Clio, twice-married and unlucky in love, has become a realist. What she craves above all is stability for her son, Alex. This means she should marry her lover, Philippe, a cultured Frenchman with a large and conventional family. However difficult it is to cope with his perfectionist ways, not to mention his terrifying mother, Clio must not rock the boat. She's a tour guide and when she takes rugged Canadian Joe around the battlefields of France, her tidy life begins to unravel again.
