This is an incredibly dark suspense thriller about a family with secrets. At surface they seem like an everyday family; one whose struggles make them more devoted. Their son Wenzhou is simple and does not know his own strength when excited. His new nanny Xiao Xiu runs off for greener pastures. Convinced something bad happened to her, Chen Youxi escapes from the orphanage to seek her out. She discovers that twelve years ago, there was another gone girl from the Li household; their daughter Wenwen. She infiltrates the Li household as a miraculously returned Wenwen and pulls at threads that conceal old secrets.

This drama starts strongly and moves at a transfixing pace throughout. The drama's strongest feature is that it keeps you guessing until the penultimate episode even though there are only three knowable suspects. While the story is gripping, the plot could be tighter from the mid-way point where small holes emerge. It suffers most in the whydidit behind Xiao Xiu's disappearance. The motive is not firmly established enough to be convincing. I rewatched the reveal a few times and suspect that something was cut out. I also did not like how Youxi tries to stage a confession trap again after the first one went so terribly and consequentially wrong. It is just lazy plot design although not inconsistent with the character's desperation to get answers. There are other small holes that add up to render this short of the masterpiece it had the potential to be.

What is exceptional is the characterisations and the mind-blowing acting. The entire cast delivers in spades. Mei Ting deserves an award for her ruthless, manipulative and multi-faceted Liao Suifang. The subtext behind her cat and mouse interactions with Youxi where they both knew they were on to each other is breathtaking and worth re-watching. Her conflicted feelings for Li Chengtian and Wang Chongjiang and how Wenzhou's ultimate welfare plays into it resonates. Her Suifang made me feel suspicious, angry, repulsed and curiously sympathetic. Similarly Wang Yanhui's Li Chengtian is also masterful - at face an affable, quiet, beaten man; a love consolation prize and a desperately seeking father... with an aura of hidden menace. The ties that bind this painful triangle together are so messy and yet almost inevitable. They keep secrets; deep dark secrets from one another and themselves. Between the three older characters, we see how relationships fracture over time and even the most normal people have dark sides but with different bottom lines.

Against incredibly layered veteran actors, the young cast can hold their own. I am not a fan of Dai Xu's brand of comedy but I really enjoy him in a serious role as Cheng Xu. After The Heart of Genius I had strong reservations over Zhang Zifeng but she convinces as this lost orphan hell bent on finding her only anchor in this world. But it is Du Yusen's Wenzhou - at times harmless and affectionate, full of simple childlike truths and at times scary as hell that steals the show. Guo Cheng also emerges here as a young actor to watch - his Cheng Wei is very charismatic and the way he lapses seamlessly into Guangzhou dialect adds dimension to his characterisation. The dynamics and chemistry between Youxi, Cheng Wei and Wenzhou is as light as the ones between the three older characters is dark. All the lost children in this story end up found in some way to end this sinister tale on a less dark note.

I have not enjoyed a Chinese suspense thriller this much since The Bad Kids. It is overall not quite at the same level but I can easily rate this a 8.5/10 with the acting worth that rare 10/10.
