They are captured by the Mahars, who keep primitive humans as their slaves through mind control. David falls for the beautiful slave girl Princess Dia (Munro), but when she is chosen as a sacrificial victim in the Mahar city, David must organize the humans to rebel and save her.

Russell, "the most probable meaning of Mahārāshtra would therefore seem to be ‘The country of the Mahārs.’".
