Borderline

Free on YouTube.   Don't let Charles Bronson's presence discourage you.  Yes it is an action movie (sort of) and very entertaining.  It is mostly a Border Patrol officer trying to find the killer of another officer, but it really shows in a non-lecturing way how illegal aliens are exploited by businesses and individuals who want cheap maids, coyotes, and corrupt Mexican officials. 

Even those of us who are opposed to illegal immigration would like an honest way to do this: background checks, a process that does not enrich lawyers, and a process for controlling the volume to avoid driving down wages of lawful residents (many of whom are Hispanic, both citizens and permanent residents).
