When Reverend Danforth comes to town with promises of healing the sick and injured by channelling God's power, most of the citizenry of Walnut Grove are agog at the things he professes to be able to do.
In his large tent, he shows them how the power of God will heal the blind, the sick and the lame and very few people want to hear the wise words of Reverend Robert Alden anymore when he counsels against believing in Reverend Danforth's claims.
When the Reverend "cures" a young boy of appendicitis, the town is convinced and flock to his spiritualist meetings for cures and strength of their own. Things turn sour, however, when the boy later dies and Charles, among others from the town, see the Reverend performing the same 'healing' on people who were with him in Walnut Grove - actots hired to portray the sick.
Soon, Reverend Alden has his shame-faced flock back and things return to normal with the realisation that a young boy died because people would not listen to the Reverend Alden or to Dr. Baker.
