Banking on Heaven is a documentary film which exposes the largest polygamous enclave in the United States (located in Colorado City, Arizona) and its leader, Warren Jeffs.

In the Latter Day Saint movement, a temple is a building dedicated to be a house of God and is reserved for special forms of worship.
 A temple differs from a church meetinghouse, which is used for weekly worship services.
 Temples have been a significant part of the Latter Day Saint movement since early in its inception.
 Today, temples are operated by several Latter Day Saint denominations.
 The most prolific builder of temples of the Latter Day Saint movement is The Church of Jesus Christ of Latter-day Saints (LDS Church).
 There are 157 operating temples (which includes 2 previously dedicated, but closed for renovation), 12 under construction, and 13 announced (not yet under construction).
 Several other variations of the church have built or attempted to build temples.
 The Community of Christ operates two temples in the United States, which are open to the public and are used for worship services, performances, and religious education.
 Other denominations with temples are the Apostolic United Brethren, the Church of Christ, the Fundamentalist Church of Jesus Christ of Latter-Day Saints and the Righteous Branch of the Church of Jesus Christ of Latter-day Saints.

The Latter Day Saint movement (also called the LDS movement, LDS restorationist movement, or Smith–Rigdon movement) is the collection of independent church groups that trace their origins to a Christian primitivist movement founded by Joseph Smith in the late 1820s.
 Collectively, these churches have over 15 million members.
 The vast majority of adherents belong to The Church of Jesus Christ of Latter-day Saints (LDS Church), with their predominant theology being Mormonism.
 The LDS Church self-identifies as Christian.
 A minority of Latter Day Saint adherents, such as members of the Community of Christ, believe in traditional Protestant theology, and have distanced themselves from some of the distinctive doctrines of Mormonism.
 Other groups include the Remnant Church of Jesus Christ of Latter Day Saints, which supports lineal succession of leadership from Smith's descendants, and the more controversial Fundamentalist Church of Jesus Christ of Latter-Day Saints, which defends the practice of polygamy.
Warren Steed Jeffs (born December 4, 1955) is the President of the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS Church) and a convicted felon currently serving a sentence of life plus 20 years.
 His prison term is the result of being convicted in 2011 of two felony counts of child sexual assault.
The status of women in Mormonism has been a source of public debate since before the death of Joseph Smith in 1844.
 Various denominations within the Latter Day Saint movement have taken different paths on the subject of women and their role in the church and in society.
 Views range from the full equal status and ordination of women to the priesthood, as practiced by the Community of Christ, to a patriarchal system practiced by The Church of Jesus Christ of Latter-day Saints (LDS Church), to the ultra-patriarchal plural marriage system practiced by the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS Church) and other Mormon fundamentalist groups.
Rulon Timpson Jeffs (December 6, 1909 – September 8, 2002), known to followers as Uncle Rulon, was the President of the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS Church), a Mormon fundamentalist organization based in Colorado City, Arizona, from 1986 until his death in 2002.
Wendell Loy Nielsen (born c. 1941) was, according to documents filed with the Utah Department of Commerce, the President of the Corporation of the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS Church), based in southern Utah.
 The FLDS Church, first incorporated in 1991, does not require the church president to be its Prophet.
 However, traditionally the President of the FLDS Church was also the religious head, or Prophet.
 Warren Jeffs officially resigned as president of the church on December 4, 2007, but his status as Prophet is unknown.
