My Best Friend's Exorcism (2022) Spoiler-Free Summary – What It's About

In the summer of 1988, a time of mixtapes, roller rinks and the glow of neon, a handful of teenagers navigate the ordinary rhythms of high school while the world around them hums with the restless energy of a decade on the brink of change. The film captures that nostalgic backdrop with a palette of pastel sweaters, cassette tapes and late‑night drive‑ins, allowing the everyday to feel both familiar and slightly off‑kilter, as if an unseen current is waiting to ripple beneath the surface.

At the heart of this world is Abby Rivers, a fiercely loyal best friend whose life revolves around her close bond with Gretchen Lang. Their friendship, forged in shared secrets and whispered confidences, feels as solid as the denim jackets they wear. As the two girls drift through the awkward rites of adolescence—first crushes, cliques, and the pressure to fit in—their connection becomes a quiet anchor amid the swirling trends and teenage turbulence.

Orbiting them are a colorful cast of peers: the thoughtful Margaret Chisholm, the outspoken Glee Tanaka, the charismatic yet enigmatic Wallace Stoney, and the oddly sincere fitness influencer Christian Lemon. Even the well‑meaning guidance of Sister Kathleen and Brother Morgan adds a layer of adult perspective to the teenage swirl. Their interactions are laced with the humor, jealousy and camaraderie that define any close‑knit group, hinting at deeper undercurrents without spilling their secrets.

When Gretchen begins to exhibit unsettling changes, the tone shifts from light‑hearted teen drama to a pulse‑quickening mystery. Abby senses that something far more sinister than typical high‑school drama has taken hold—a vague, malevolent presence that whispers through the halls of their suburban world. Determined to protect her friend, she turns to an unconventional source of help, an unusual exorcist whose methods are as unconventional as the era’s fashion. The film balances the tender intimacy of friendship with an eerie, growing dread, inviting viewers to wonder how far a bond can stretch when faced with an unseen, escalating supernatural threat.
