Steep (prod Sony?)
or
The Story (prod The Ski Channel)
Unless you're talking about just showing your friends newschool movies. Both of the above cover most types of skiing and have some narrative. The thing about showing newschool movies like Refresh etc to non-skier friends is that, although they will always find the tricks and stuff impressive, they don't truly appreciate the difficulty of the tricks and dedication that is put in. The two movies above, or at least Steep (cause I haven't seen The Story entirely), not only show some newschool skiing but also attempts to explain the passion that drives skiers, no matter what discipline of skiing.
