The story starts 500 years from the 20th century, when an ensemble gang called the Black Marketeers begin hunting the dinosaurs to serve their unknown purpose. The continuous hunting process has made the dinosaurs violent and now they have started attacking villages and people.
In order to get things sorted again, mechanic and shaman Jack Tenrec, diplomat and explorer by profession Hannah Dundee, friend and engineer Mustapha Cairo, and mysterious Mess O'Bradovich have decided to team up against the evil deeds of the Black Marketeers. The protagonists reach "the City in the Sea" where they suspect the whole hunting network being operating from. They finds themselves surrounded by Vice Terhune's men. Vice orders his men to attack the group to keep them away from the business. Fighting all the men, the four finally get their hands on Vice Terhune.
