Satan's Slaves 2: Communion (2022)

In 1955, newspaper journalist Budiman is summoned by his friend Heru, a police commander, to Bosscha Observatory, where a cult ritual seems to have taken place overnight: dozens of exhumed corpses lay prostrate facing a framed portrait of Mawarni. Heru has been instructed to prevent publication of this story, so as not to damage the country’s image in light of the upcoming Bandung Conference, but he insists that Budiman publish the story through obscure magazines.

In 1984, Rini, her brothers Toni and Bondi, and their father Bahri have been living in a flat at the dilapidated Mandara Apartments in Jakarta for the past three years. Bahri seems to work odd jobs all day and always carries a briefcase, which he keeps locked at home. Budiman, now editor-in-chief of an occult magazine, receives Heru’s suicide note in the mail along with photos and drawings that suggest an upcoming cult activity at Mandara; they also reveal that Bahri was one of the police officers who took Budiman to see Heru in 1955. Meanwhile, the lift at Mandara malfunctions and falls, killing many tenants. At night, a storm rages and floods the building, trapping the tenants inside. Rini consoles Wisnu, a child whose mother was killed in the lift. Wisnu tells Rini that he and his mother used to communicate in a mysterious sign language that they learned from an occult book, so that his abusive father would not understand.

The flood cuts off electricity, and supernatural forces start harassing the tenants. In the building manager’s flat, Bondi and his friends find photos of the cult congregating every 29 years on 17 April, which is the next day. Meanwhile, Toni enters a hidden room inside a flat, where he finds photos of his deceased mother Mawarni, who is identified as Raminom. Toni shows them to Rini, and they recall that Mawarni started looking like Raminom after embarking on a musical career. Rini opens Bahri’s briefcase and finds severed human fingers. They find Ian, their deaf youngest brother who was taken by the cult, in a top floor flat. Wisnu speaks with Ian in the mysterious sign language, and Ian says he is a friend.

The corpses rise and, with Raminom, haunt the remaining tenants to their deaths. Surrounded by the undead, the siblings and Wisnu run into Bahri, and are captured by the cult members. They awaken on a secret top floor, where the cult has begun their communion. Ian commands the cult and cheerfully executes Bahri by quartering. Budiman arrives, fires at the cult members, and repels Raminom. In the sign language, Wisnu instructs the cult to stop, as Rini strikes Ian unconscious. The siblings and Wisnu escape via boat with Budiman, who explains that Bahri persuaded Mawarni to join the cult in 1955 to have children and stardom. Bahri tried to get themselves out, but the cult required him to murder one thousand people to do so. As a result, Bahri had since been working as a sniper, performing extrajudicial killings for the Indonesian government. Budiman explains that tonight's communion was only part of a bigger plan.

The next day, Darminah and her husband Batara arrive at Mandara. She expresses disappointment that they were not present at the communion, but he reassures her that everything went according to plan. A photograph on the wall reveals that they attended the 1955 Bandung Conference, and they do not appear to have aged since.
