Looks like a heist movie, then suddenly zombies. Hiroyuki Sanada is in it, so will definitely give it a watch.

The premise is:
There's a zombie that breaks out of containment and results in the infection of everyone in one city. People escape the city and the gov traps the zombies inside the city. There's casinos and other goods stuck in the city too, so the heist is set up to retrieve money in a safe within one of the casinos stuck in the zombie territory.
