Bring field content from "parent" node to "child" node

What I need to do is bring a field from a parent node to a child node (I know that a node only has a parent through the menu). Something like the following...

<?php 
	$myactive_trail = menu_get_active_trail();
	$parent = $myactive_trail['2']['link_path'];
	print $parent->field_video[0]['filepath'];
?>
