英国BBC王牌IP《9号秘事》中国版，是BBC Studios在中国大陆首部与本土公司共研共创，针对中国市场量身打造的创新单元剧。每集一个独立故事，在封闭空间、规定时长下，展现人性反复，黑色幽默加极致反转，创造意料之外又情理之中的脑力盛宴。

Wearing identical dresses, the same bouquets and deliriously happy, older couples stride out of a communal wedding. In Xian, China, getting remarried en masse is nothing unusual. It is also a celebration of what was previously impossible owing to socio-economic conditions. Now, however, elderly couple Li and Nie are facing up to death. In small ways and big: a dying female friend has her eye on a potential suitor for her husband; their fridge breaks down; the grave of Li’s deceased first wife has to be vacated. Guilt-ridden about her death, he gladly offers her a final resting place in the grave set aside for him and Nie. Maybe there will even be some space left, so Nie’s late husband can join them?
