Mantis

Mantis (2025) is a South Korean crime-action thriller you can watch online on iFILM. When the boss of the biggest assassin-staffing agency dies, the whole trade for hire collapses into chaos, and the old rules stop protecting anyone.

A top killer nicknamed Mantis could have signed with any rival outfit. Instead he bets everything on the childhood friend he's never stopped loving, and the two of them launch a business of their own just as every contract turns into a turf war. Im Si-wan plays the ice-cold professional; Park Gyu-young is the partner who's every bit as lethal. Director Lee Tae-sung keeps the rhythm brutal — a fight crammed into a tiny apartment, a chase, a clean finish, then silence before the next job.

Sleek, hard-hitting action set in the same world as Kill Boksoon. Made for anyone who likes Korean action with no soft edges. Stream Mantis (2025) online on iFILM.
