Un groupe d'adolescents férus de technologie diffusent leur fête sauvage en ligne. Mais quand Brie se réveille, elle est toute seule.
Un sinistre message souriant lui dit que ses amis sont chacun piégés dans des boîtes séparées. Ils ont tous leurs téléphones, mais si quelqu'un tente d'appeler la police ou ses parents, la peine sera mortelle.
R
(Under 17 requires accompanying parent or adult guardian 21 or older. The parent/guardian is required to stay with the child under 17 through the entire movie, even if the parent gives the child/teenager permission to see the film alone. These films may contain strong profanity, graphic sexuality, nudity, strong violence, horror, gore, and strong drug use. A movie rated R for profanity often has more severe or frequent language than the PG-13 rating would permit. An R-rated movie may have more blood, gore, drug use, nudity, or graphic sexuality than a PG-13 movie would admit.)
