A bold feature from writer-director Li Yang, also producer, film editor and focus puller, who is not afraid to expose the 'every-man-for-himself' corruption and swindling situations of China's miners' conditions. Seems like a sad story, yet its plot progression is as taut a thriller and chilling as it is straightforward, with its dauntless depiction of the ugly, the callous and the innocent. Amorality and moral strength are at play here, and the script was written with dramatic turns akin to the basics of human nature, be it circumstantial greed, abandoned pleasure, filial attachment, or unabashed dreams. A gutsy, gritty film - a natural thriller without cutting off the threads of humanity. Congratulations: Your vote has been cast
