Indonesia has plenty of urban legends about places where something terrible happened during construction, but Project Sacrifice takes one of the darker ones and turns it into a full supernatural thrille – originally titled Tumbal Proyek, the film is built around the idea that human sacrifices are secretly used to protect major construction projects – which is a pretty horrible thing to imagine when you’re looking at one of those enormous developments going up around you.
And I quite like the choice of setting here – a half-built construction site already has something slightly unsettling about it at night, and add some black magic rituals underneath and you’ve got plenty to work with.
A Father Died Here, and Yuda Wants Answers
Yuda, whose father died under mysterious circumstances connected to a huge construction project, has never really accepted the explanations surrounding his death, and eventually decides to investigate the company behind the development with members of his own family, where he starts uncovering evidence that the missing workers are connected to something much more sinister, with the construction project supposedly being protected through human sacrifice.

The Rumour Behind the Film
The title Tumbal Proyek refers to a long-running Indonesian belief that human sacrifices can be used to protect or guarantee the success of major construction projects, and the idea has appeared repeatedly in Indonesian urban legends, particularly around large developments, bridges and other major construction work – the stories vary, but the basic fear is usually the same – something has to be sacrificed so the project can be completed safely or remain standing.
Obviously, there is a huge difference between an urban legend and reality, but these stories have become part of Indonesian popular culture and horror storytelling, so Project Sacrifice takes that familiar fear and asks what would happen if the legend were actually true.
The film makes good use of the fact that construction sites are strange places even without supernatural activity, because they’re temporary environments full of unfinished buildings, dark rooms, machinery, empty floors and areas that aren’t normally accessible to the public.
That gives Yuda plenty of places to investigate while also making it believable that something could be hidden there – a place that’s actively being built, with people working there every day and money being poured into the project, and that’s what makes the idea of a secret ritual underneath it all particularly grim.
Greed Is Part of the Horror
There is also a fairly obvious human element to the story here too, as the people behind the project aren’t sacrificing workers because they’re simply evil for the sake of being evil – they’re apparently willing to do it because they believe the sacrifices will protect the development and ultimately protect their investment.
The construction project represents money and progress, but underneath that is a belief that human lives can be treated as expendable if the end result is valuable enough, which will give Yuda’s investigation something beyond simply finding out who killed his father – he’s uncovering a system where people are willing to keep killing because they don’t want their project to fail.
Cast and Production
Project Sacrifice is directed by JeroPoint, who also receives a writing credit alongside Sandika Gusti and Shinta Puji, and the film stars Kiesha Alvaro, Callista Arum, Karina Suwandi, Eduward Manalu, Rayn Wijaya and Ruth Marini.
It is produced by Dee Company and features Dolby Surround 7.1 audio, with the film released in Indonesian cinemas on May 13, 2026 – Dee Company has been behind a number of Indonesian horror productions, so the film is coming from a company that clearly knows there is an audience for this sort of supernatural material.
An Indonesian Urban Legend Gets the Horror Treatment
The idea of a tumbal – a sacrifice offered to appease or satisfy supernatural forces – appears in Indonesian stories in different forms, and the construction version takes that belief into a modern environment here – you’ve got cranes, concrete, investors and massive development projects, but underneath all that modernisation is an old fear that refuses to disappear.
That’s a good fit for Indonesian horror because the film can put traditional supernatural beliefs directly against modern life rather than having to choose between the two.
The connection to Yuda’s father also gives the story a reason to keep moving as well, as he’s already got a personal reason for wanting to know what happened, so once workers start disappearing, the investigation becomes more urgent, but the family connection means there is something at stake before the supernatural horror really gets going.
And I think that’s important for a mystery like this, because if Yuda didn’t care about the answer, there wouldn’t be much reason for him to keep digging once things became dangerous.
