In the wee hours one evening in a small Southern town, 17 grade school classmates got up from their beds, left their homes, and ran off into the night. As the stunned community grapples with the inexplicable-from the kids’ suspected, fragile teacher (Julia Garner) to the dad (Josh Brolin) for whom the authorities aren’t moving fast enough-the truths behind the phenomenon will reveal in jaw-dropping fashion. Zach Cregger’s stylish shocker co-stars Alden Ehrenreich, Benedict Wong, Austin Abrams. 128 min. Widescreen; Soundtracks: English Dolby Atmos TrueHD, DVS, French Dolby Digital 5.1, Spanish Dolby Digital 5.1; Subtitles: English (SDH), French, Spanish; featurettes.
