The plot is very basic; The world is destroyed (in 2011) and only 1% of humanity survives in the city of Bregna. The city is being led by the Goodchild dynasty for 400 years and it's about 2400 when the people of Bregna start to revolt. At least, a small group called the Monicans. Aeon is sent on a mission to kill dr. Trevor Goodkind and they fall in love, and save the world.
Well, actually, there's a bit more to it (but don't wanna put up the spoilers), making it a good watch after all.
The movie is not an original, but an adaptation of the original animation series that aired on MTV in the early 90's
