no TopFlix. The Book of Mormon is a musical comedy with music, lyrics, and book by Trey Parker, Robert Lopez, and Matt Stone. The story follows two missionaries of the Church of Jesus Christ of Latter-day Saints as they attempt to preach the faith to the inhabitants of a remote Ugandan village. The earnest young men are challenged by the lack of interest from the locals, who are distracted by more pressing issues such as HIV/AIDS, famine, female genital mutilation, child molestation, and oppression by the local warlord.
