Young single mother has two sons and a daughter by three different fathers who are completely unaware of having fathered them. Anne's mother conjures up a plot to make everyone involved to go on a beach holiday in Mexico at the same time so that her grandchildren could meet their fathers and their new families.
This is quite entertaining and has the added bonus of an absolutely gorgeous Élodie Bollée (probably around 13 at the time of filming). May not be to everyone's taste but I enjoyed this immensely.

Lots of sources so should get pretty quick.
enjoy...
