Husband never sleeps

Erika, like many graduating seniors, receives a gift from her parents for successfully passing her exams - a trip to Paris. When she meets a charming college student in a town on the Seine, she immediately falls in love with him and has an unforgettable moment with him...
For Pierre, however, it is just a pleasant summer episode, which he admits without shame when he says goodbye to her. When Erika returns home and finds out that she's pregnant, he decides, that it, who is the father of the child, he won't tell anyone. But the sight of an illegitimate grandchild is completely unacceptable to Erica's mother, and so she makes her daughter's life a living hell.
