Two pairs of Mormon missionaries from America live in a beaten-up apartment in the Dutch city of Haarlem. Their personalities are distinctly different. Appropriately, the most responsible one, Elder Johnson, is the District Leader and oversees their efforts. His companion, the vain Elder Van Pelt, seeks to become the assistant to the mission president (the top post available) as soon as possible, and he receives letters from three girlfriends he left behind. The capable Elder Rogers has become disillusioned and inattentive to his duties ever since a previous missionary companion returned to America, looked up and married Elder Roger's girlfriend. As a result he is simply marking time until he returns home in a few weeks time. The three meet Elder Roger's new companion, Elder Calhoun, in the train station. This new elder is a nerdy but enthusiastic "greenie" that has just arrived from the Missionary Training Center (MTC) in Utah. Unfortunately his training did not give him much fluency in the Dutch language, but as luck would have it, the first person he approaches to proselytize is a fellow American named Kyle. In the weeks that come, Elder Johnson and Van Pelt increasingly irritate each other while in contrast Elder Rogers and Calhoun begin to relate in a positive fashion as they teach Kyle about the Mormon faith.
