In this episode, Challenger, Summerlee and Veronica save a little girl from drowning and Summerlee has to give her mouth to mouth resuscitation. Tolmac, of the Christec people, brands Summerlee a witch for bringing the girl "back to life". The Christecs have mingled the Catholic and Aztec religions, with a touch of Conquistador Inquisition, to form their theocracy. Veronica gets away to summon help from the others, but Challenger has to act as Summerlee's lawyer ~ if found guilty, both men will be burned at the stake.
