In this special BBC schools radio episode, not heard since its original 1976 broadcast, the TARDIS takes the Fourth Doctor and Sarah back in Time to witness stages of the Earth's development.

If his threats to endanger the stability of Earth have any substance, the existence of mankind itself is in question!
