Coma people rejoice soon!

I see a movie. In some clinic on some deserted island in Japan, patients who fell into coma in various times, wake up at the same time. One of them, afraid of all the advance of the technology, and... Idk... women head of hospital thinks they took over the world, so he kills all of the staff, and then coma communists fight coma republicans, and north Vietnamese fight south and..

I initially read 'coma' as 'China'. Needless to say I had to do a double-take.

What is with all the medical news?
