The plot of the film is about a young woman who was kidnapped and is held captive in an unknown location with only a computer to access for help via social media. She also has no food and only a creaky shower to drink water. Has its intense and claustrophobic moments.
As a thriller, the film is relatively mild. There's no nudity, almost no profanity, or any bloody or graphic violence. The film would definitely get a PG-13, if only for the intense subject matter.
