He travels back in time to get an insight into Earth's past and arrives on an uncharted island in the Pacific Ocean. Three unnamed scientists exploring the island at the time discover him where they thought was a prehistoric ancestor of mankind. They bring him back with them to civilization.

The Chinese capture him with sleeping-gas, but once fully mutated the Missing Link becomes too powerful
