Captain America: Civil War Trailer Breakdown - 40 Things You Need To See

9. A Metaphor For The Entire Film

The security forces chase Cap who chases Black Panther who is chasing Bucky, who is trying to vault over a moving car.

That's basically the entire story of Civil War in one moment. Aside from the car bit. Notice the Audi in the background: this is presumably right before Cap is caught and surrenders. Meaning Bucky probably gets away, and Black Panther disappears after him.
