The story revolves around a girl who is one of 160 people with a mysterious disease known as Medusa who are chosen to go into cold sleep in hopes that in the future, a cure for the disease may be reachable. Unfortunately the group awakens nowhere near as far in the future as they'd hoped, and the disease has wrought destruction at a rate no one could have anticipated.
The survival horror flick is due out in 2010 and will be directed by Kazuyoshi Katayama, best known for helming The Big O and the 1988 Appleseed OVA. It'll actually be his first directorial gig since 2000's Argento Soma.
The six-volume manga has been released in English in its entirety by TOKYOPOP in North America, so if you want to look into it and decide if this is a flick you'd like to see, that's probably the best outlet. I know I'm gonna go out and buy it, because it sounds pretty cool.
