Strangers from Hell

An aspiring crime writer named Yoon Jong-woo moves into a residential block in Seoul that looks ordinary from the outside but hides a web of unsettling, almost predatory neighbors. The quiet routine of rent and work is upended when small, hard to explain incidents begin to mount, prying at the edges of his sanity. As the corridors close in and the dim stairwells feel like traps, Jong-woo finds himself drawn into the lives of those who inhabit the same building, each masking secrets cooler and crueler than the last.
