Girl in the Box trailer: Zelda Williams stars in Lifetime movie

Hitching a ride from a friendly couple turned out to be the biggest mistake Colleen Stan ever made, and EW has an exclusive trailer for Girl in the Box, Lifetime’s new fictional version of her real-life nightmare.

Zelda Williams, daughter of the late Robin Williams, stars opposite Zane Holtz as Janice and Cameron Hooker, a maniacal couple who kidnap Colleen (Addison Timlin) and hold her captive for almost a decade under their bed in a box the size of a casket.

“You’re only here to take the pain,” Janice tells Colleen amid scenes of torture, tears, screaming, and a disturbing number of leather cuffs.

“What would you do if someone did this to your daugther?” Colleen asks, her hands tied above her head. “I’d kill them,” responds Holtz’s character, who demands she call him “Master.” Colleen continues: “Then how do you think my dad feels?”

Girl in the Box premieres Saturday, Sept. 10 at 8 p.m. ET on Lifetime. Watch the exclusive trailer in the video above.
