Le Septième Ciel plot
The fair is held in Houblonnes, a small provincial town. Brigitte de Lédouville has for some time been tirelessly engaged in a number of good works that she finances herself. Now she wants to collect 20 million for the construction of a medical institute in South Africa. But she does use a very unorthodox method to get the necessary money: she always seduces rich people, takes large sums of money from them and then takes them to "the seventh heaven". The ritual is always the same: the men fall victim to an ingenious system of electrocution and are then buried in the garden of their property.
