See if anybody can find this!
Father(CEO), mistress, daughter and young male on private plane. Father flying crashes into mountain, father and mistress die. Daughter and guy escape and haul out survival gear and setup camp, personnel interaction etc etc. No one can find them or plane! Young girl miles away sees signal fire on side of mountain and tells grandfather,resulting in rescue! Daughter and young male marry in Canada and are secreted into States and into hiding until bad guys trying to takeover father's company are subdued etc etc. Does any of this sound familiar??
