After visiting an evolution exhibit narrated by guest star Griffith, Flanders pushes Mayor Quimby to appoint Reverend Lovejoy as a "Mortality Czar" in charge of spreading the theory of creationism. Darwin's theories are quickly outlawed and Lisa finds herself as the only supporter of the scientific theory. After holding secret evolution classes, Lisa is arrested and retains Southern lawyer Wallace Brady to help defend her beliefs in front of a judge. While Flanders is on the stand in court, Homer's antics cause him to crack under pressure and he calls Homer an ape, which leads the judge to believe Homer resembles the missing link - putting a monkey wrench in the prosecutors' case.
