Four large cannons, named after the four Evangelists, blast the attacking Northerners to pieces from a hill. Sergeant Chesterfield and Corporal Blutch are to disguise themselves as a priest and a village fool and head to the hill where Captain William N. Pendleton, who is also the pastor of the Episcopal Church, is in command. Will the two of them succeed in their mission to silence the four Evangelists Luke, John, Mark, and Matthew?.
