The new trailer for "Batman" focuses heavily on "Bat and Cat," or the titular superhero (Robert Pattinson) and Catwoman (Zoe Kravitz). In the trailer, she sings, "Sounds good to me."

In the latest edition of The Dark Knight Story, Bruce Wayne has been stalking the streets for two years, striking fear into the hearts of criminals. The lone vigilante has only a few trusted allies, including Alfred Pennyworth (Andy Serkis) and Lieutenant James Gordon (Jeffrey Wright). But it seems he has a new partner in crime-fighting: Selina Kyle, aka Catwoman.

The two begin by punching each other, but seem to end up on the same side as they chase after the disruptive Riddler (Paul Dano).

The new trailer offers fresh footage along with intriguing details. Here are three things we have learned:

1. The Riddler's motives

The trailer provides further clues as to the Riddler's purpose in spreading the seeds of destruction and death in Gotham City. Selina says that his latest riddle is "all about the Wayne family." It is "The Sins of the Father?" and includes the phrases "The update is a lie." Not only that, but the Riddler seems to know that Bruce Wayne is Batman. His revenge may have begun against Bruce's parents, perhaps over how they amassed their fortune, and then moved on to the next generation.

2. Alfred lied

The staunch butler had always been a loyal friend. Bruce accuses Alfred, "All these years you have been lying to me." What is that lie? And is it connected to the lie the Riddler is telling? It is also interesting to note that later in the trailer, Alfred says, "You are still Wayne." This further suggests that the secret is related to Bruce's parents.

3. The Batmobile in Action

We have seen the redesigned Batmobile in previously published images, but this is the first good look at it in action. This version is much bulkier and sturdier, more like a muscle car than a sleek sports star. And it looks like it will have to navigate some tough situations.

Batman opens in theaters March 4.
