Rayne and her friends lived somewhat normal lives until one day an alien warned them of his race's oncoming invasion. Fortunately, he trains them to fight it back.

Unfortunately, Nox, King of Cinder, accounted for this in his plans to claim Earth.

Our five fighters never expected the aliens, affected by sunlight, to attack them at school during the day. Unprepared, they find the horde are much harder to kill than they were taught in training. And their trainer suspiciously disappeared four months prior to the assault.

If the good guys can't stop the invasion now, it will spread across the world. And Nox will use Rayne to make it happen.
