What Is Granny About?
The story centres on Jung Suk Ja, an ordinary grandmother whose entire world revolves around her grandson Kwon Yong Hui. When he is left in a coma by the notorious Black Star Mob — who walk free despite overwhelming evidence — she is approached by two men who offer to train her so she can take justice into her own hands. Hesitant at first, she eventually agrees, and begins hunting down her targets one by one.
Think of it as a grandma-led revenge thriller. The premise alone is enough to make this one of the most compelling new additions to Netflix’s growing action catalog.

Why the Casting Is a Perfect Fit
Lee Jung Eun is one of the most reliable and beloved actresses working in Korean streaming today, having previously appeared in Netflix projects including Heavenly Ever After, The Trunk, Daily Dose of Sunshine, Our Blues, and Juvenile Justice. Watching her pivot into a full action-revenge role is the kind of casting surprise that makes the internet sit up and pay attention. whats-on-netflix
Kim Mu Yeol joins her as Seo Yeon U, one of the men who trains and assists Jung Suk Ja on her mission. The two previously shared screen space in Juvenile Justice, so there is already a real working chemistry between them to build on. whats-on-netflix
It is worth noting that the production had a slightly rocky road — Sanae Pictures reportedly walked away from the co-production after a dispute over profits, leaving Studio Dragon as the sole producer. The series is still very much on track, however, with cameras rolling from July 5. whats-on-netflix
