Empty Hands.

Claire Endicott throws a wild party and her father walks in to find her flirting with the very married Milt Bisnet. In an attempt to straighten her out, Endicott sends Claire to the Canadian northwoods, where his field engineer, Grimshaw, is working. While fishing, Claire is swept over the rapids and Grimshaw tries to rescue her. Both of them wind up in a remote gorge, and Grimshaw goes about building a hut as a shelter.
