The New Eve (1999)

Camille is an emancipated 30-something woman who has no desire to settle down and have a family, preferring to coast along on a succession of ephemeral relationships and one-night stands. However, her lifestyle fails to satisfy her fully, and in a moment of depression she runs into a complete stranger, Alexis, whom she instantly falls in love with. Alexis, alas, is married, with two children, and works for the Socialist Party. None of this is going to deter Camille though…
