There is a bleeped use of strong language ('f**k') as well as use of milder terms ('bullshit', 'shit', 'bloody', 'damn').

There are scenes of moderate threat in which rescuers struggle to extract a group of children trapped in a flooded cave; rescuers battle poor diving conditions, flooding and low oxygen levels. There is real footage from inside the cave showing the children looking underweight and exhausted along with scenes of flooding caves and tense news reports chronicling the mounting dangers. There are also rescue re-enactments, one of which shows an adult man with no diving experience thrashing about under the water, and an unconscious child being transported underwater in diving gear. Moments of threat are accompanied by focus on the resourcefulness and determination of both rescuers and survivors.
