It's possibly an American comedy. Three friends (one white woman, one black woman, one white man) go on a vacation to a skiing or snowboarding resort, vowing not be concerned with their work for a while

One of the women is a prostitute and she breaks their vow with a man she meets at the resort.
Another plot point is a rare snowboard with only a few of them left in existence.

this is usually my sweet spot. was it a comedy? when did they see it? the woman friend was the prostitute?
