Three quarters of the planet Earth is covered by water. A majority of the planet's solid surface is abyssal plain, at depths between 4,000 and 5,500 metres (13,100 and 18,000ft) below the surface of the oceans. The solid surface location on the planet closest to the centre of the orb is the Challenger Deep, located in the Mariana Trench at a depth of 10,924 metres (35,840ft). Although a number of human activities are conducted underwater—such as research, scuba diving for work or recreation, or even underwater warfare with submarines, this very extensive environment on planet Earth is hostile to humans in many ways and therefore little explored. But it can be explored by sonar, or more directly via manned or autonomous submersibles. The ocean floors have been surveyed via sonar to at least a coarse resolution; particularly-strategic areas have been mapped in detail, in the name of detecting enemy submarines, or aiding friendly ones, though the resulting maps may still be classified.
Johnny (Richard Egan) and his wife Theresa (Jane Russell), along with mercenary Dominic Quesada (Gilbert Roland), priest Father Cannon (Robert Keith) and Gloria (Lori Nelson), the boat owner, search for sunken treasure in the Caribbean. While on a dive they come across a wreck that they assume holds treasure. When they resurface they are confronted by a local boat with an unhealthy curiosity in their activities. In their effort to find funding to raise the wreck they discover that what they are looking for is a 17th-century ship that contains a life size solid gold Madonna encrusted in precious gems and that it lies in a different underwater location. And so, they set about to acquire it. However, it's on the edge of a precipice in shark infested waters and they are not the only ones after it.
The album version of the song has a slow, ambient arrangement focused primarily on strings performances. Like nearly all Delerium singles to date since "Silence", the single release put greater emphasis on a number of tranceremixes commissioned by Nettwerk Music Group in order to promote the song through club play.
The music video for the song was directed by directors collective Twobigeyes. It was aired in two different edits, which were set to the Above & Beyond remix (the more common version) and the Rank 1 remix.
