So it’s a movie about a man, maybe a missionary or researcher or explorer, if I remember correctly he didn’t seem to want to be wherever he was. I believe it takes place in South America or Mexico (the native characters were lighter skinned, not black but not white, and I’m pretty sure not Native American either because I remember accents. Hawaiian is a possible)

the only scene I remember is a young woman from this tribe pulls down her skirt in front of this man in attempt to seduce him, in hopes that he (an American) will father a child for her who would then be an American citizen and able to have a better life. He is tempted but refuses, and has no further romantic interactions with this woman

i think the movie was released in late 90’s to early 00s
