You know what they say… Nothing tests a friendship like a bit of demonic possession. 

For bffs Abby and Gretchen, surviving their teenage years gets a little bit harder when Gretchen accidentally becomes a vessel for evil. Or to put it another way…

“She looks copacetic, but she’s cuckoo for cocoa puffs.”

Check out the trailer for My Best Friend’s Exorcism below.

Here’s the official synopsis of My Best Friend’s Exorcism from Prime:

Surviving the teenage years isn’t easy, especially when you’re possessed by a demon. It’s 1988, and best friends Abby (Elsie Fisher) and Gretchen (Amiah Miller) are navigating boys, pop culture, and a paranormal force clinging to Gretchen like a pair of neon legwarmers. With assistance from overly confident mall exorcist Christian Lemon (Christopher Lowell), Abby is determined to compel the demon back to the pits of hell—if it doesn’t kill Gretchen first. 

The film adapts the best-selling novel by Grady Hendrix, with a script from Jenna Lamia (Good Girls, Awkward). Damon Thomas (Killing Eve, Penny Dreadful) directs.

My Best Friend’s Exorcism stars Elsie Fisher (Eighth Grade, Despicable Me), Amiah Miller (The Water Man, War for the Planet of the Apes), Cathy Ang (And Just Like That…, Over the Moon), Rachel Ogechi Kanu (Cheer for Your Life), and Christopher Lowell (GLOW, Promising Young Woman).

You can stream this 80s horror comedy on Prime Video September 30.
