Batman v Superman opens with Batman's origin and fast forwards to Bruce Wayne coming to Metropolis during the Superman/Zod fight, but that's just setting the stage for that character. From there the script turns its attention to Superman heavily, and it examines the implications of Superman in the real world. The main action takes place a couple of years after the end of Man of Steel, and Superman has been busy in the meantime, becoming the hero we know and love. Clark Kent and Lois Lane have moved their relationship forward to the point where they live together. Clark is still working at the Daily Planet, although it's unclear if he's loving his assignments - he's tasked with covering a Metropolis/Gotham football game when he would rather be writing about Batman.
Very early in the film Lois is in the Middle East following a story when Superman shows up to help her out. This becomes something of an international incident as other nations view Superman as a tool of the United States. China, for instance, doesn't want him in their air space. It's an interesting look at how a being like Superman would be viewed on a global scale.
