Hey guys I’m having trouble resembling a name of a movie that I remember watching as a kid. It has to be ether a late 80s or early 90s movie. Here what it’s basically about.

Two white brother’s go and live on a Indian Reservation in Alaska I think. Anyways they they team up with a local girl and her brother to stop bad men from tearing down secret totem poles and then There’s this part where they are trapped in a cave by the ocean and the only way out was throw a under water passage that sea loins keep coming in and out.

Also I remember watching it on tv a lot when I was a kid and it was in english.
