A black cloak of forgetting, suppressing and covering has descended on the events that took place in Bangkok in spring 2010. Black as the night of complete darkness in which the film opens.

By night, the rubber plantation also comes across as enticing and full of secrets, until lurid reminders of the bloody massacre flash up.
