People said, man in his fortieth no longer suffers from perplexity. But Bian Liang at 42 suddenly finds himself more and more perplexed, which makes him feel at loss. It is a year of life crises: as an aggressive father, he is resisted by his unambitious son;his way forward is blocked by career bottleneck; and his harmonious family foresees some sudden changes. All at once, Bian Liang finds his wisdom and experience learning from life over the past 40 years are unable to solve these problems, and even his way of coping with life seems to be all wrong. Confused and helpless, he,as a conscientious middle-aged man, can't but seek antidote to crises while moving forward hard. As he takes apart and reconstructs his past life, he eventually makes up with his son, wife and friends, and turns on the right way of life.
