Darkness: Those Who Kill (Seasons 1–4)

Darkness: Those Who Kill (2019) is a Danish crime thriller you can watch online on iFILM — bleak Nordic noir built around the hunt for a serial killer.

Seventeen-year-old Julie has been missing for six months, and investigator Jan is desperate to give her mother some kind of answer. Then he finds the remains of another girl the same age. When a third disappears, the pattern is undeniable: one man is taking them, and he won't stop. Jan brings in profiler Louise, and to catch up they have to climb inside the killer's head and reason the way he does.

Part of the long-running Danish "Those Who Kill" franchise, it leans into the genre's signatures — grey light, wet motorways, a quiet that unsettles more than any scream. Natalie Madueño carries the psychological weight as Louise. Easy to recommend if you're into The Bridge or The Killing. Stream Darkness: Those Who Kill (2019) online on iFILM.
