I went to a theater to watch ‘AVATAR.’ At first, I’ll let you tell the outline of AVATAR.

It’s the story in 22nd century. People spreaded their frontierism into outer space. Jake was ex-Marines, and had his legs broken fighting. Under spreaded frontiers for space, Jake stood in his brother’s shoes, which are the researches and negotiations for Na’vi, the aboriginal people living in the planet PANDORA.
