Thirty seconds isn't a lot of time, but this 30-second clip of Harry Potter and the Deathly Hallows Part 2 is enough to show us what Voldemort has in store for Harry: a magical beatdown.
In this scene, Hagrid has been captured by the Death Eaters, and Harry approaches Lord Voldemort in a forest. It's fairly obvious that Voldemort has Harry right where he wants him ... outnumbered, with his one ally in chains and few witnesses.
It doesn't look good for poor Harry. You'll have to wait to July 15 for the movie's release (or, ya know, just read the books) to find out what really happens. But here's a hint: The title of the clip is "The Killing Curse."
