Like many horror thrillers out there, the upcoming Netflix K-drama Parasyte: The Grey features action sequences in every episode, but South Korean actress Jeon So-nee says they're different from your average fight scenes.

The series, which is based on Hitoshi Iwaaki's hit manga of the same name, replaces the original high-school-aged protagonist for a young woman named Jung Su-in, played by the 33-year-old. She gets attacked by a parasitic organism named Heidi and begins co-existing with it.
