Satan's Slaves: Communion (2022) Spoiler-Free Summary – What It's About

In the sweltering summer of 1955, Budiman Syailendra, a seasoned investigative journalist, is summoned to the isolated heights of the Bosscha Observatory. There he meets his old friend, police commander Heru Kusuma, who has stumbled upon a baffling tableau of exhumed bodies arranged in a macabre display beneath a portrait of a figure known only as Mawaran. Against the backdrop of a nation poised on the world stage for the upcoming Bandung Conference, the two men grapple with the weight of a secret that could tarnish a country’s reputation. The atmosphere is thick with colonial‑era tension, a pervasive sense of unease, and the faint whisper of forces that defy rational explanation.

Three decades later, the story shifts to the cramped, aging complex of Mandara Apartments in Jakarta, where Rini and her brothers Toni and Bondi eke out a fragile existence under the watchful eye of their enigmatic father, Bahri Suwono. Budiman, now the editor of a niche occult magazine, receives an unsettling package that hints at a lingering darkness tied to the events of 1955. The apartment tower, with its creaking walls and flickering lights, becomes a crucible where personal grief, hidden histories, and an undercurrent of the uncanny converge. The siblings, each bearing their own burdens, find themselves drawn together by a shared curiosity about the strange symbols and cryptic messages that begin to surface around them.

The film weaves a slow‑burning tapestry of dread and intrigue, balancing the gritty realism of post‑war Indonesia with an almost dream‑like, supernatural haze. As the characters navigate the thin line between journalism, superstition, and family loyalty, the audience is invited to feel the palpable tension of secrets waiting to surface. Every hallway, every whispered rumor, and every lingering glance suggests that the past is not finished with those who dared to look—and that the truth, whatever it may be, threatens to upend the fragile world they have built.
