Fox has released a new trailer for A Good Day to Die Hard.  Usually at this point, the trailers begin to reveal the basic plot (and some go too far and reveal the whole movie).  However, the fifth Die Hard is a little over a month away, and I still don't know what the plot is beyond "McClane n' Son fight bad Russians."  The Die Hard movies have never been complex, but the villain always has a clear motive, so we know what John McClane is trying to stop.  I think the bad guy in this movie wants nukes or something, but even that seems kind of vague.

Hit the jump to check out the trailer.  The film stars Bruce Willis, Jai Courtney, Sebastian Koch, Yulia Snigir, Cole Hauser, Amaury Nolasco, Megalyn Echikunwoke, Anne Vyalitsyna, and Mary Elizabeth Winstead.  A Good Day to Die Hard opens February 14th.

Here's the official synopsis for A Good Day to Die Hard:

Iconoclastic, take-no-prisoners cop John McClane, for the first time, finds himself on foreign soil after traveling to Moscow to help his wayward son Jack–unaware that Jack is really a highly-trained CIA operative out to stop a nuclear weapons heist. With the Russian underworld in pursuit, and battling a countdown to war, the two McClanes discover that their opposing methods make them unstoppable heroes.
