Family History

In French cemeteries, "perpetuit" only lasts for a hundred years. If the deceased's family wants to keep their dead buried, they must pay the rent. 

If not, the municipality will excavate the tomb to liberate the space for a new family.

After the latest excavation, Robert and Clothilde find themselves faced with a ghost much older than themselves - along with the daunting task of solving a century-old mystery.

Is it still possible to find eternal rest for their new friend?
