One scene where they go skinny dipping and he is shown stripping down. His naked butt is shown in closeup for a few seconds and then again in a flash as they are walking to the swimming hole.

Bear attacks are quite graphic.

A man hits his foot and later in the film it is shown covered with blood.

A decaying corpse of a deer is seen with flies over it.

A man cleans fishes by ripping them off and then cooks them.

Lots of the Lord's name in vain. A lot of f-bombs.

Alot of f@#$ words

A man smokes.

A couple drink beer, wine etc. During their trip.

While the first half is suspenseful, the second half is quite intense and scary.

The thought of getting lost in the middle of nowhere could frighten some.

This is an intense film which is done very realistically and could be intense for weak hearts.
