Madea swears she’s done with ghosts, goblins, and foolishness. But when her grand-niece Tiffany invites her to a weekend Halloween retreat in the mysterious “Old Willow Mansion”—a supposedly haunted estate deep in rural Georgia—Madea finds herself once again caught in a mix of chaos, scares, and side-splitting laughs.

What begins as a family-friendly Halloween getaway turns into a night of frights and foolishness when strange things start happening—objects moving on their own, eerie laughter echoing through the halls, and mysterious messages warning, “GET OUT… before MIDNIGHT.”
Madea, of course, isn’t scared—she’s mad. Armed with her purse, frying pan, and sharp tongue, she sets out to uncover the truth behind the haunting. But what she doesn’t expect is that the “ghost” haunting the mansion may have a personal connection to her past…
With her usual crew—Joe, Aunt Bam, and Hattie—along for the ride, Boo! 3 delivers a mix of gut-busting humor, family chaos, and surprisingly heartfelt moments as Madea learns that sometimes, the scariest ghosts are the ones inside us.
