G.I. Joe: Retaliation Premiere Trailer [Video]

Little has been revealed about the plot other than that it will feature the G.I. Joe Team coming into a conflict with Zartan, Storm Shadow and Firefly. Zartan (who is last seen in disguise as the President of the United States) has now got the world leaders all under his thumb, warheads headed towards innocent populaces, and some new heavies on the payroll to keep G.I. Joe at bay. [Source]
