What I remember is this, a teacher (I think) took a group of students high school level maybe camping or hiking. The teacher got injured I think he fell down a mountain, later one of the girls was attacked by a bear. So they have two injured now. There was something about one of the kids who knew a lot about survival and was boiling urine or something for the others to drink to stay hydrated.
