During a sleepover one night, teenage girls share stories with each other about things that frightened them.

What's the scariest story you know? An elderly woman-seemingly addressing us from the future-looks back on a harrowing night in the 1990s when she and a group of teenage girlfriends gathered for a sleepover to swap spooky tales and dabble in some occult mischief. But what begins as seemingly harmless adolescent fun is only a prelude to a horror that remains tantalizingly unseen and unspoken. Unfolding in a trancelike haze of dreamy dissolves, spectral double exposures, and audacious long takes, this visually sublime fusion of avant-garde aesthetics and classic old-dark-house atmospherics bristles with the hushed, candlelit air of a séance.—BAMcinemaFest
