Our take
Mantis is a TV-MA Korean action thriller about a secret society of contract killers in chaos after old rules collapse. Expect frequent f-word and motherf-word dialogue, murder-for-hire as the central premise, bloody knives, and talk of killing minors as a taboo line. Funeral scenes and loss of a former colleague add emotional weight. Strictly for mature adults and older teens; glamorized assassin culture is not kid material
Story (may spoil tone)
The secret society of contract killers falls into chaos, unleashing a new breed of assassins. With old rules in ruins, who dares claim the shadows?

Talk after watching
- The film treats killing as a business with codes and betrayals. How does turning violence into work change moral responsibility?
- Jae-yi inherits a legacy she did not choose. What does it mean to escape a family or mentor's path?
- Assassin guilds operate in shadows while ordinary life continues. How do stories like this reflect real power structures?
