Questions

What is the plot?

The Siege at Thorn High begins in 2009 with a boy named Edwin drawing under a tree during a school break. Another boy, Panca, asks Edwin to deliver a letter to his sister Silvi. This early scene establishes Edwin’s connection to the school and the students.

In 2027, Edwin, now an adult, works as a substitute teacher at Thorn High, a juvenile detention center for troubled teens. He is there searching for his missing nephew, a promise he made to his sister on her deathbed. Edwin struggles to connect with the unruly students but eventually identifies his nephew among them, suspecting Khristo because of their shared talent in drawing.

As Edwin tries to navigate the school and protect his nephew, a violent anti-Chinese riot erupts in the city, trapping everyone inside Thorn High. The students inside become hostile, and a brutal group led by Jefri emerges, determined to eliminate Edwin and his nephew. The school quickly turns into a battleground.

Edwin finds a vent in the room where he and Diana are hiding and uses it to escape briefly to disable the jammers blocking communication. He manages to break the jammers to call for help and takes keys to the emergency exit. Meanwhile, Jefri kills a boy named Sim in the bathroom after Sim tries to escape. Edwin hides during this confrontation and then rushes to the security room to disable the jammers.

Edwin sends a boy named Rangga out with a key to unlock the back exit, hoping to create an escape route. After sending Rangga and his father out, Edwin and the group wait 15 minutes but realize the father and son are still inside. Jefri brings them out forcibly but sends another boy to fetch gasoline. The boy encounters police outside, who are called away due to the riots, leaving the school isolated.

Inside the school, Jefri burns Rangga’s father alive. Rangga tries to get help by rushing to the school entrance but is stopped by two boys. In the ensuing chaos, Gerry kills Rangga. Sim then annoys Jefri, who calls him a crybaby before killing him later in the bathroom.

Edwin continues to move through the school, using the vent system to navigate and evade the violent students. Near the security room, a boy suggests using a blowtorch to break open a locked door, indicating the increasing desperation and violence inside the school.

Throughout the siege, Edwin’s key decisions—such as disabling the jammers, securing the emergency exit keys, and attempting to send Rangga out—drive the plot forward, highlighting his efforts to survive and protect his nephew amid the chaos.

The film ends with the school still under siege, the fate of Edwin, his nephew, and the remaining students left uncertain as the violent conflict inside Thorn High continues.
