NETFLIX has acquired its first online drama series produced in China.

The U.S. entertainment giant unveiled a deal Thursday with Youku Tudou, the flagship streaming video service of Jack Ma’s Alibaba Group, for worldwide rights outside of China to “Day and Night,” a 32-episode detective drama series.

Critically praised and commercially successful in China, the show has generated more than 4 billion views on Youku since its local online premiere Aug. 30.

“Day and Night” follows the investigation of a grisly unsolved murder. The police detective in charge is recused from the case when it is revealed that his twin brother is the top suspect. Spurned by the suspension, the detective then quits his job — only to be recruited by the new lead investigator as a secret consultant. The title is a reference to the dual but often uncertain identities of the two brothers — one ostensibly righteous by day, the other allegedly evil at night. Directed by Wang Wei, the series stars Pan Yueming as both brothers. Netflix plans to make “Day and Night” available in all of the 190-plus countries and regions where it is active.

Last April, Netflix sold the local streaming rights to a batch of its originals to Beijing-based video service iQiyi. (SD-Agencies)
