Jack's settlers

Jack at the weekend decided to go to the amusement park. It was crucial for visiting the Tunnel of Doom which somehow teleported him in ancient times. There, he met with Aboriginal tribe and becomes their leader. Applying their knowledge of our hero of our time improves their life. Build the house, introduces and teaches agriculture to tame and domesticate animals. But his dream is to return home. And it will come from him or not - time will tell.
