In 1879, Gustaf Berglund feels an intense calling to leave his native Sweden to become a pastor to the Swedish immigrants in America. Much to the displeasure of his family and rejection by his sweetheart, Gustaf bravely sails away to New York to fulfill his dreams. Encountering severe obstacles when he arrives, Gustaf is often at the point of giving up and returning home. However, he perseveres and graduates from seminary near Chicago in hopes of becoming an admired pastor in a prestigious church in the Midwest. He is devastated when he is assigned to a small congregation on the frontiers of Texas. There he is taught by faithful pioneers and fierce sinners what it truly means to be a pastor.
