Original Sin 原生之罪 comes from director Raymond Yip (Cook Up A Storm), and stars Zhai Tianlin (The Advisors Alliance) as a lawyer fresh out of prison and Yin Zheng (A Chinese Odyssey: Love You for Ten Thousand Years) as a skilled detective with a hidden past. The two begin as archenemies, yet eventually team up to solve the mysteries together.

Costars include Li Ruoning, Bai Bing (Only Side By Side With You) and Cherry Ngan (Monster Hunt 2). The web drama is supervised by Han Sanping (Let the Bullets Fly, The Grandmaster) and will air on iQiyi sometime this year.
