Nowadays, the monsters of old times have made a comeback. Called by the eldest of the family, Cerberus, several other members of the same family have been freed from the Underworld, through passages across the world, and no one knows what they intend to do. One man does have an idea though, Richard Touillos. The very powerful and eccentric multi-billionaire behind Touillos Industrie has been monitoring the actions of these monsters since Cerberus was freed from Hell by one of his teams of researchers. Convinced that they will try to dominate the world, he ensures that the main survivors of previous encounters with these creatures are in his company, in order to learn as much as possible about these survivors from ancient times and better defeat them. Having a veritable army of international mercenaries under his command, as well as several private islands around the world, he's convinced that he can prove that man remains the king of the world ! However, he had better not forget a few things : for these creatures, nothing is more sacred than family... and nothing can make them more powerful !
