Step Over the Edge (1976)

When Trevor (Scott Wallace) signed up for the 3-week wilderness journey with a group of other young believers, he expected an enriching time. What he found, in his judgmental opinion, was a group of misfits who shouldn't even qualify as Christians. As the trials on the trails unfold, each member of the group starts to see their own strengths...and weaknesses. Each, that is, except Trevor.
