Two best friends, one of whom decides to take revenge for a bad joke played by the other, against a backdrop of tragedy and violence. In the world, 230 million children do not have birth certificates, and these "ghost" children find themselves excluded from society and prey to the worst abuses. In Benin, the mayor of Dogbo has concluded a decentralised cooperation partnership with his Belgian counterpart in Roeselare on birth registration. Strong actions are carried out in terms of equipment, recruitment, training and awareness raising. On a mission to Dogbo, the Belgian delegation is taking into account cultural differences in order to make the project a full and frank success.
