We are the masters of the underworld, the slaves become masters, the conquering exploits of power! The world of mining is divided into two categories; those who are with the Boss, and those who dig. Lucien digs... Until the day when the bowels of the earth reveal to him a world populated by creatures of frightening proportions. By mixing realism and fantasy, Romain Baudy dynamites the boundaries between imagination and political narrative to offer us a punchy adventure.
