The Love Test (2006)

Elsa and Sabine have been best friends for years. They are both single, but Sabine thinks that she has found the man of her dreams. Since both women have been disappointed in love before, they decide to put Thierry to the test: does he truly love Sabine as much as she loves him? Or is she just another passing fling in his life? Does he have someone else? To test Thierry's faithfulness and sincerity, Elsa passes herself off as Sabine's country cousin and asks Thierry to put her up for a few days.
