Earth Final Conflict 1x04 - Avatar

Early in the 21st century, a race of aliens, the Taelons (often referred to as "The Companions"), travel to Earth and take up residence in limited numbers. The Taelons possess highly advanced technologies, many of which they share with humanity, seemingly out of generosity and good will. As a result of these advances, disease, war and pollution are nearly eliminated within three years of their arrival. Despite this, some question whether the Taelons' motives are as benevolent as they appear, and a resistance movement forms to halt the Taelons' ever growing influence on humanity.
