Ten years after her husband He Shan disappeared, Moss Flower (played by Jiang Qinqin) was about to start a new life, but fate pushed her into another desperate situation. She was driven away from the tea garden by her lover's (played by Chen Jianbin) mother, and then she was deceived by her closest sister Jinlan into the pyramid scheme "Butterfly International". The mother was addicted to it, which made her son Mu Lian (played by Wu Lei) who was looking for his father and saving his mother physically and mentally exhausted, while Butterfly International grew like a vine, planting the seeds of the devil in the hearts of countless people. Moss Flower also changed, from her clothes to her words and deeds, she was like a "newborn", and her crazy behavior surprised Mu Lian. When the mother fluttered in the dream like a butterfly, the son tried every means to rescue her... How can this purgatory on earth be escaped? Can the modern version of "Mulian saves his mother" succeed?
