Netflix Korea will be bringing its latest film, 'Unlocked', to viewers worldwide on February 17. 

Based off of a bestselling Japanese novel, the Korean film adaptation starring Chun Woo Hee, Siwan, Kim Hee Won, and more offers yet another thrilling perspective into the dangers of having one's most private information stored in just one device, a smartphone. 

The story begins when Na Mi (Chun Woo Hee), an ordinary office worker, loses her smartphone. Afterward, she becomes embroiled in a series of unbelievable events, as her phone ends up in the hands of Jun Young (Siwan), a mysterious young man. Kim Hee Won also joins the story as detective Ji Man, investigating a murder case. While surveying the crime scene, Ji Man discovers traces of his own son, Jun Young, and begins suspecting that his son may be the real culprit.
