Three Year 9 students perform a routine experiment in a school laboratory and travel thousands of years back in time, finding themselves in the middle of the Aboriginal Dreamtime. They land on a big rock in the prehistoric Australian outback.

They experience fear, tribal rituals and even death, all the while learning the ways of our indigenous ancestors. However, throughout their ordeal, the boys never stop thinking about their own time and ways to get back home.
