Now then, it's best - I think - to just accept that there is very, very, little plausible science to this save-the-planet movie. The format, and the story, have oft been done by Hollywood before so it's not top of the originality tree either - but it's still quite a watchable and well produced story of a group of Chinese trainees who must raise their game when they find themselves trying to save the infrastructure being built to help save the planet from terrorists.
