# Whistle - Parental Guide
This R-rated horror film involves high school students who unleash a cursed Aztec whistle with deadly consequences. Expect strong violence, intense scares, frequent profanity, and moderate sexual content. Due to the graphic horror elements and mature themes, it's not suitable for children under 17 without parental accompaniment, and we don't recommend it for younger teens.
Synopsis
A misfit group of unwitting high school students stumble upon a cursed object, an ancient Aztec Death Whistle. They discover that blowing the whistle and the terrifying sound it emits will summon their future deaths to hunt them down.
