Professor Shonku cannot dismiss without proof the possibility that unicorns do exist somewhere on earth. In fact, Charles Willard, a fellow scientist, claimed to have actually seen them in Tibet, but, unfortunately, died shortly afterwards. So, when Shonku learns that another expedition is starting off for Tibet, he jumps at the opportunity to trace Willard's route and find the unicorns. Tibet is just one of the exotic places Professor Shonku's exploits take him in this volume of stories. In the Sahara he comes face to face with a massive pyramid-like structure no one knew of earlier; he travels underwater in a submarine with two Japanese scientists to investigate the sudden appearance of deadly red fish that have taken to eating humans; in the caves of Bolivia he meets a primitive man who has been painting his dwelling with animal figures and strange mathematical formulae; and on a peculiar island which has appeared out of nowhere in the Pacific Ocean horrific plants suck out all his learning from his brain
