The story begins with a large group of Archelon turtles hatching in a nesting ground and beginning a trek towards the sea. An overhead shot shows that there are hundreds of these small turtles...which unfortunately attracts huge numbers of predators. Pterosaurs, mosasaurs, plesiosaurs, sharks, Xiphactinus fish and all sorts of other predators lie in wait, attacking the column of baby Archelon as they make their way down the coastline and into the water. While many fall prey to the dangers lying in wait for them, sheer numbers means that many more successfully make it past the dangers.
