During an excursion with their boat, a group of 15 young marine club members, aged between approximately 6 and 20 years, is transported to a strange world, inhabited by both humans and several kinds of dinosaurs. They quickly befriend talking pterosaur Zans and native woman Manua.
While trying to find a way back home, they learn about the strange new world in which they're stranded, discovering that the people and dinosaurs suffer from oppression by the king as well as the church's prohibition of science. They get into conflict with General Mosar, who is interested in their advanced technology and consequently have to flee from the king's army as well as the priests who try to capture Zans, who incidentally is the son of White Wing, the famous but deceased leader of the rebellion.
Jura Tripper provides examples of:
