The film is based on extensive research of Moskoff to discover the location of the Ark of the Covenant. He is convinced that the Ark is buried underneath the Temple Mount in Jerusalem but is not under the Dome of the Rock, as is commonly conjectured. Moskoff also discounts other hypotheses that suggest that the Ark is in the Vatican or Ethiopia. Moskoff's thesis is following that of the 12th century Jewish codifier, Maimonides and substantiated by the British engineer and archaeologist, Sir Charles Warren, amongst others. In 2010, Moskoff produced a short documentary based on his research, entitled The Soul of Mount Moriah.
