Mountain village sisters Sun Ru and Chen Yue lead different lives due to different choices.
In order to escape poverty, the eldest sister Sun Ru used marriage as a springboard to marry a disabled demolished household in the city. With her intelligence and ruthlessness, she started from a cigarette shop, clung to the rich and powerful, and grabbed billions of wealth in the real estate wave. For this reason, she planned her sister's marriage, abandoned her husband, alienated her family, and eventually betrayed her family. When the backer collapsed, everything she built collapsed instantly, leaving only the money and the cage.
Cousin Chen Yue was once pushed far away by fate. She divorced and ran away because she was envious of her cousin's "success", but she fell into a loveless love and was abandoned when she became ill. During the five years of fighting cancer, the company of her daughter and the generous support of her ex-husband made her realize that true love is far better than vanity. She defeated the disease, returned to her ordinary family, and gained inner peace.
The story outlines a profound picture of desire, conscience and choice through the intertwining fate of the two sisters for decades. Sun Ru continues to conquer the outside world but is desolate inside. After going through hardships, Chen Yue finally finds happiness in the ordinary. They are like two sides of a mirror, reflecting different understandings of "the mountain beyond the mountain" - a dangerous peak pointing to wealth and status, and a hometown leading to the heart and love. When everything is settled, what really traps people is never the mountain of origin, but the mountain that they cannot cross in their hearts.
