Need movie title with possible native americans

There is only one specific scene I can remember which makes this quite tricky to search.

‘Man who ends up being hired as a guide is basically guiding people through a landscape or forest and bumps into some native americans/tribe who he pretends not to know, but in reality he has a very good relationship with them’

This was in order to somehow trick the group he was guiding (money or so on)

Please help me find the movie name.
