Daniel continues his visit to Lagny-sur-Marne, a small town where extraordinary events took place. Joan of Arc is said to have performed a miracle there on her second visit to Lagny. And the abbey-church of Saint Pierre once harbored a great secret: a nail from Jesus's cross. Unfortunately, the nail was lost, but not forgotten, as it now features on Lagny's coat of arms.

Lionel shows us around a family farm that spans three generations. This traditional dairy and cattle farm takes good care of its animals, which enjoy a special "cow wash." Nursing cows are allowed a break from milk production prior to calving, and nothing is left to chance as the sex of the newborn calf is predetermined thanks to artificial insemination.
