Bong Joon-ho's Mother trailer online
The film tells the story of the mother of her son who has been wrongly fully convicted for the murder of a girl. He was heavily coerced into confessing to the crime and quickly imprisoned. It seems it's up to his mother to track down the real killer.
Seems interesting, although the trailer below doesn't really pull me into the story much more than the teaser. We'll have to wait for more, and perhaps an English language trailer too.
