It's a movie that's set in Australia, but the characters don't sound Australian because of the words they use. The movie is about adventure in general, but Sasha, the main character, kayaked in blue jeans. Jeans are pretty heavy when wet; they are the same jeans she uses for climbing.
Ben, the villain, was able to track Sasha so well that it felt almost impossible. one time somehow he gave up finding her few feet away, and then teleported back to his camp, taking a bath naked, she went back to that exact camp to get his canoe and got trapped instead of escaping through other ways.
Anyway, as you can see, it's not exactly a great movie. However, Charlize Theron plays a neurologically shut-in widow, and Taron Egerton plays a sadistic character. The latter carried the film, but I wouldn't recommend it despite their acting and the beautiful Australian wilderness.
