There is no gore in this film.
Due to the nature of this film, abduction and murder are main themes, but we do not see any murders being comitted.
When a box is found near the beginning, we see the mummified remains of a child.
A man pours cement in a pit and it is implied that a child is locked into a wooden box which was placed inside the pit.
There are a couple of scenes of fighting but only with fists.
