Constance, Kentucky. 1910. There is fear in the air and a comet in the sky. A mother and son roll into town with big words and a cart full of anti-comet merchandise. The mother is not counting on a battle of conviction with the town's priest, and her son is not expecting to fall for the priest’s daughter. A storm rages, the comet races nearer, and faith and science stake their claims for the people of Constance.
