When you just want to spark a fatty, kick back, and enjoy life, the one thing you don’t need is something harshing your mellow. Well, in the new action comedy, American Ultra, that’s exactly what Mike Howell is up against.

But his buzzkill is of a different sort than what most of us are used to. See, while Mike thinks he’s just your average small-town stoner, he finds out that he’s actually a highly-trained government sleeper agent. Pretty cool, right?

Well, not exactly. The reason Mike figures this out is not because he’s being activated for some slick top-secret mission. It’s because he’s targeted for extermination.

Bad vibes, bro.

Now, Mike has no choice but to try and get himself and his girlfriend (Kristen Stewart) out of this little jam-slash-deadly government operation. Luckily for them, he starts to recall his repressed training, and soon Mike the stoner gives way to Mike the stone cold killing machine.

For those of you who can’t stomach another blockbuster sequel or bad studio reboot this summer, you’re in luck. This fun and refreshingly original film hits theaters Friday August 21. You can check out the trailer below and then let us know what you think. To learn more about the film and grab advanced tickets, head on over to the official American Ultra site here.
