The Mantis: Original Sin (2025) — Korean Drama

“To catch the mantis, you must become the branch.”


Synopsis: Seoul panics when a killer stages victims to mirror an insect life cycle—egg, nymph, molt, wings. A tireless prosecutor pairs with a forensic entomologist whose estranged mother—the imprisoned hitwoman called The Mantis—will consult only for her. Murders tick with

lunar phases; clues surface in neon alleys, jjimjilbang boiler rooms, rooftop hives, and a Han River service tunnel. Each tableau points to a sealed case tagged “Original Sin,” where a false confession bought peace. With the next molt hours away, the hunters must choose: save one life, or expose the lie that made them

.

Review: Lean, nerve‑tight procedural with aching family stakes and tactile science; Seoul‑noir mood hums. Score: 8.6/10.
