“Who is the Murderer” is a suspenseful criminal investigation web drama co-produced by Beijing Akiyo Technology Co. and Beijing Starlight Guoyun Culture Co., directed by Sun Hao and starring Zhao Liying, Xiao Yang, and Dong Zijian. The drama tells the story of a serial murder case that took place in the city of Haizhou. After the truth has been sealed for sixteen years, people who are inextricably linked to the unsolved case are waiting for the truth to emerge in their own unspeakable secrets.

In the cold winter of 2001, a murder case occurred in the affiliated hospital of a printing factory in Haizhou City. Rookie policeman Leng Xiao Bing (Xiao Yang) and his senior rushed to the scene after receiving a report, but accidentally faced the murderer of the serial murder in Haizhou City. Leng Xiao Bing was timid and afraid to shoot. The murderer fled from the scene and killed his senior, Li Lan. Another witness at the scene is a victim, orphan Xia Mu (Dong Zi Jian), hiding under the bed. In order to stay in the police force, Leng Xiao Bing concealed the fact that he did not dare to shoot, Xia Mu did not expose him either. So far, the murderer has been in the hiding, and the Haizhou case is still pending.

Sixteen years later, Xia Mu came to the force for an internship. Threatening with the fact that Leng Xiao Bing didn’t dare to shoot, he coerces Xiao Bing into investigating the case with him. Just as the two pointed their suspicions at the father of the psychologist Shen Yu (Zhao Li Ying), Shen Yu also launched a plan to create a crime of imitation. Then a corpse that had been dead for more than sixteen years caused the three of them to fall into the dark night of souls. The three finally joined forces to trap the real murderer.

The official release of the poster, which appears to be the three main cast posters, the poster reveals little information. The whole poster is hazy and gloomy, Zhao Liying is in the C position of the whole poster, she black female professional dress, looks very smart and strong, eyes are cold and sharp, but also through a deep and mysterious. Xiao Yang is examining the camera as if conveying a message, while Dong Zijian looks relatively relaxed, but the eyes hide an indescribable sense of melancholy as if there is some story to tell. Overall, the poster seems to reveal nothing, but the suspenseful atmosphere is well set.

The entire trailer has no lines and no text messages, but the very beginning of the picture brings the audience into a tense and secretive atmosphere.

The camera begins with a quiet and deep distant scene, three different characters appear, they seem to be in the light, but is shrouded in darkness, the deep door frame to confine them, although it is not possible to see their expressions, but can feel the complex relationship between the characters.
