In the Cartel Business update for PAYDAY 2, the gang is contacted by an old associate, Vlad, who has deposited some personal items in a small town bank in Mexico. The bank is owned by a Mexican crime cartel that Vlad has had a recent falling out with, so he needs your help to retrieve his valuables.
The DLC consists of a one-day heist set in the Mexican town of San Martín, as well as some new content including new weapons, skins, voices, mods, and so much more. More detailed information for the update can be found here.
You can check out the trailer for the San Martin bank heist above.
