I too am currently writing a film. I won't give you an idea, since I think doing so would be wrong - but what I can do for you is show you the introduction to my screenplay to spark your own imagination.
Now, you have to understand that I'm not giving you permission to use my plot. Rather to stimulate your imagination with it. Either way, it kinda sucks, and it wouldn't make you famous:
Narrator: Our Story begins on the shores of Lake Nibiru [in upper Lemuria].
>>Show footage of Glenmore reservoir regional area...[in spring/summer]
Lemuria was a great civilization and continent that once thrived more than 78 000 years ago at the time of the Atlanteans. However advanced, the two civilizations both shared their differences. The Atlanteans were scientific and cosmopolitan, while the lemurians were peace loving, spiritual and artistic people. Though aware of each other, they held to their separate paths and chose not to associate w/each other.

Nevertheless, both civilizations held responsibility of a dangerous tool – the ruby stone, a small but powerful elemental quintessence that connected the spirit world to third dimensional earth. With the stone, each civilization was capable of channeling dark spiritual energy as a source of pollution free fuel to power their homes and lives. Despite this, the stone had its shortfalls.
The ruby stones were operated in a simple fashion. Ancients understood that ascended spirits reside in Amun Ra (The Sun God, source of all life) which emits divine white light. Since the light requires quintessence to be absorbed (the ruby stone) could be used as a medium to capture this most powerful and dangerous energy whilst fusing quanta through the tiny ruby stone.
The stones were, in short, the center of each civilization. In theory they were capable of harnessing limitless power but such relied on availability of the sun. Energy could not be harnessed on cloudy days. Approximately every 25 000 years, the earth changes climatic cycles from an optimum of warm and wet weather to a spell of cold and dry weather known as an ice age. Between cycles a cleansing hundred year period of precipitation and winter is staple, leading into the process known as glaciation.
Unfortunately for the Lemurians, the zenith of their civilization teetered on the edge of the climatic cycle and into the cleansing period. With no sun left to fuel their ruby stones, they made a last fatal attempt to harness energy from the spirit world. Both the Lemurians and the Atlanteans coaxed their scientists into tuning their ruby stones to a higher absorption frequency so that any light reaching the surface of the earth could be fused at much greater volatility. Such measures were never needed before but deemed perfectly safe as the quintessence was invincible. Or so they thought. As soon as the sun peeked through the surface of the clouds, the massive amounts of energy produced caused the stones to degenerate into plasma. Such sparked a colossal nuclear reaction in the Earths mantle and submerged the two continents of Atlantis and Lemuria, leaving behind them the present day archipelagos of Oceania and the Caribbean. A few survivors managed to escape the catastrophe and brought with them the arithmetic paradigm of the ruby stones to surrounding sub-civilizations. This mathematical oddity was known as the pyramid, and symbolized the focal point at the tip and the fusion of quanta at the base.
Though the disaster was ruinous to the face of the earth, it brought with it an even greater calamity. During degeneration of the stone, an evil and mischievous spirit known as death was able to manifest itself in physical form as its spiritual light was drawn from Amun Ra onto the earth. Death represented the volatility of weak spirits. From the disaster onward, death wandered the earth and was a slave to everything that was weak. It became a tool of obsession and served the purposes of weak individuals throughout history. Death was responsible for all great wars and misunderstanding. Death prevented the progression of civilization. And death had bewbz.
Another unfortunate by-product of the explosion occurred when a common pine had its DNA scattered with that of a Lemurians during the nuclear blast, forging an immortal pine tree with the face of a devil. This creature was soon ascribed the name Lucifer, or Frankenpine. Like death, Lucifer wandered the earth throughout the ages; however he had a different cause. Lucifer sought out a companion, somebody who was like himself – an ugly mutant that smelled like rotten fish.
Both these lost souls wandered the globe for thousands of years, nearly side by side had they been aware of the others existence. Until one day, they found themselves wandering the continent of Alberta (show scene large Alberta continent in place of North America). This brings us to present day Calgary – (fade into footage of Calgary Skyline with subscript Calgary – 2003).

In Calgary…
Begin Act 1
Now brainstorm.
If that doesn't help you, then I have only one other piece of advice. Surf the internet for a couple hours, and find something really whacky. Feed on it, and write an intro right away.
-Good Luck!
