In the future the sun tried to kill us. By trying to dry up all the oceans and water. Leaving the planet a desolate wasteland. So instead of oceans we now have vast deserts that act like oceans. Alone with these vast desserts comes unusal life. Like Giant Sand Whales called OZMA.

Lets say one day you are riding along minding your own business trying to catch an OZMA. When you see someone running from the government. After an OZMA magically appears you make sure to save this person. Who turns out to be a hot girl. This in turn makes the government come after you. Lucky for you, the ship you are on is a submarine. You soon learn that with the government's persistence that this girl is no ordinary girl. I guess the OZMA hunting is going to have to wait.
