Yoon Seo-ha, a college lecturer, is surprised to learn that her long-forgotten paternal uncle has died, leaving her as the sole heir to the family's burial ground.

In October 2022, Kim Hyun-joo, Park Hee-soon, Park Byung-eun, and Ryu Kyung-soo were cast to play various roles for the Netflix series The Bequeathed which is created and written by director Yeon Sang-ho, and the production is managed by Wow Point, a global content production company and RedPeter Films, a film company that created movies such as Peninsula (2020), Another Child (2019), Birthday (2019), Psychokinesis (2018) and Train to Busan (2016).

[14] Christopher Cross of Asynchronous Media stated that the series "is an even, but ultimately satisfying procedural that leaves plenty on the table in its search for narrative closure".

[16] Pierce Conrad of South China Morning Post rated it a 3/5 and stated that it "draws us in quickly with its atmosphere but the mystery of its central premise soon loses its lustre" and "viewers looking for full-on supernatural horror may be wise to readjust their expectations".

[19] Stephanie Morgan of Common Sense Media stated that the series' "uninspired writing will only appeal to diehard fans of horror and mystery, leaving other viewers underwhelmed".

[21] Rhian Daly of NME rated it a 3/5 and stated that "the main focus of the show, meanwhile, is let down by muddy and convoluted storytelling that rips away the power from the eerie scene-setting", continuing that "everything is largely predictable, which leaves the horror being played out on screen feeling more like a balloon slowly, sadly leaking out air than one commanding your attention (and fear) with a sudden pop", and "despite some strong performances from the actors, though, [The Bequeathed] doesn't come close to living up to the expectations around it".
