At the end of the Civil War, engineer Jim Bludso, accompanied by his friend, Banty Tim, returns home to the town of Gilgal, and discovers that his wife Gabrielle has deserted him and their son Breeches for another man. Jim is welcomed by Kate Taggart, the village storekeeper's daughter, and their attachment deepens until Gabrielle returns after being deserted by her paramour, and Jim forgives her for their son's sake. Meanwhile, Ben Merrill, an unscrupulous contractor who has built the town levee, fears that the structure will not hold the coming flood waters. Merrill destroys the levee and attempts to place the blame on Jim and Banty Tim. In the flood, Gabrielle is killed, but before dying, she exposes Merrill as the man for whom she had deserted her home. This information reaches Jim when he and Merrill are aboard the boat The Prairie Bell . In the ensuing fight, the ship catches fire and explodes. Rescued from the debris by Banty Tim, Jim marries Kate and begins a new life.
