Su Anxin, a girl from the lower city, and five companions, accidentally entered the special recruitment program of the upper city college, which is known as "the only way to cross classes".
In front of them are six admission notices and an honorary documentary "Screening" that will follow the entire process. The camera promises to record "truth" and the academy promises to give "the future".
However, under the extreme squeeze of resources and quotas, suspicion spread like wildfire. Anonymous reports, moral stains, and past scars were uncovered one by one and magnified in front of the camera.
The six people quickly became "villains" who fought against each other: selfish, short-sighted, and despicable--perfectly fitting all the stereotypes of upper city and lower city.
The documentary "Screening" was a hit in the ratings and became irrefutable evidence of the superiority of governance in the upper city. The six people were ruined and became the shame of the lower city.
It wasn't until a year later that Su Anxin's sister Su Anxi discovered another version of the story in her sister's old mobile phone left behind.
Purpose: Under the stigma, is there another truth about human nature?
