The Sin

The Sin (2024) is a South Korean horror-mystery you can watch online on iFILM. A film crew rolls into an abandoned countryside school, and the very first rehearsal ends with a young woman leaping off the roof.

Then she gets up. The corpse attacks the crew, and whatever was sleeping inside that building starts turning the dead against the living. Survival becomes the only plan. Shi-yeon, cast as the movie's lead, ends up the last one standing — and realizes she was the target all along.

Director Han Dong-seok keeps the real horror underneath the jump scares: the creatures are just the surface of an older, more personal sin. Tight corridors, damp walls, ninety-odd minutes of mounting dread. A good pick if you like Korean genre films where the truth cuts deeper than the monster. Stream The Sin (2024) online on iFILM.
