Bigoted plantation owner Marcus Spencer bullies and abuses his African work force,refusing to pay them an agreed sum. Their ally is Father Ignatius Loyola,a Jesuit priest and Spencer gets McGill to investigate him. In fact he is an ex-mercenary called Porter,believed to be dead but,after locating and speaking to Porter's father,McGill sees that he is genuinely repentant and anxious to help the oppressed Africans. For this reason,it only seems right to defy the vile Spencer and his wife and go over to the side of the angels.
