The film centers on an American named Peter Quill (Pratt) who becomes the object of a manhunt after stealing an orb coveted by the villainous Ronan the Accuser (Lee Pace).
Quill first runs afoul of Korath the Pursuer (Djimon Hounsou), who is not impressed with Quill's self-designated sobriquet of "Star Lord."
Because the Guardians of the Galaxy comics are largely unknown to general audiences, the trailer takes care to introduce the main characters, starting with Drax "The Destroyer" (WWE wrestler Dave Bautista).
We also meet the assassin Gamora (Zoe Saldana, green this time!)…
…Rocket (voiced by Bradley Cooper, though we never hear him in the trailer)…
…Groot (voiced by Vin Diesel, who also isn't heard in this trailer)…
…and Peter Jason Quill, aka Star Lord.
After the introductions, the trailer launches into a series of blink-and-you'll-miss-'em cuts of the characters in action.
We get a brief shot of Quill stripped to his skivvies and demonstrating his anger by flexing his abs.
To cover the bases, we also get a quick glimpse of Gamora without her shirt on.
We also get to see Gamora with her clothes on, wielding a sword and generally looking like you don't want to mess with her.
Drax goes on that rampage we'd heard about.
We also meet a few of the secondary characters, like Nebula (Karen Gillan), a ruthless and quite bald pirate.
We see someone who could be Ronan the Accuser, but we never see his face.
