From the introduction: The Sting is a CAPERS adventure for 1st-level law enforcement characters. It is set in Atlantic City, although it can be adapted to any other city with ease. ... The characters are a group of federal agents working for the Bureau of Prohibition, closing in on a major operation that will take Nucky Johnson down a peg from his high perch in Atlantic City. They will be opposed by Nucky’s crew and a few smaller names as the agents try to seal up as many holes in their operation as possible before the big sting goes down.
