River focuses on Hikari (Misako Renbutsu), a woman in her early twenties whose boyfriend was murdered in the Akihabara massacre of 2008. Clearly unable to function due to grief, the film follows Hikari as she wanders the Akiba streets, aimlessly. She runs across a photographer and is even recruited to work in a maid café (though she quits immediately). Finally, she meets a young man whose seems to be as damaged as she. His horrible break from his parents has left him bitter but now he must deal with the fact his town has been destroyed by the 3/11 tsunami.
Meditative, touching and rather meandering, River is not for everyone; but for those who like quiet, contemplative work this will be food for thought.
