Jesse Eisenberg and Kristen Stewart were an interesting pair in Adventureland, and now they're back together again as an onscreen couple in American Ultra — albeit an explosive one. Documenting the story of small-town stoners Mike (Eisenberg) and Phoebe (Stewart), a couple on the verge of getting married, American Ultra starts with Mike discovering that he is a trained assassin (without even knowing it) while working at a convenience store one evening.

The trailer gives us preposterous action scenes, and tongue-in-cheek references to some classic secret agent films. It's Eisenberg like we've never seen him before — bloodied and boozy. Stewart serves up some acting chops as a damsel in distress, but not an entirely helpless one. See it first below.

  

American Ultra will be out in American theatres in August.
