Captain Fowler:  These six victims had their throats cut . They were mid- to upper - level drug dealers . _ Two _ were teenagers . They were all murdered in the past few months when a new drug ring muscled in and took over most of the uptown heroin and cocaine trade .
Kate Beckett: A new drug ring ? Well , who are they ?
Captain Fowler: The commissioner asked me to find that out and shut them down . But they 're invisible , these guys . They do n't use banks , so we ca n't follow the money . They make sure their street dealers never meet their suppliers .
Kate Beckett: So when you bust a dealer , he does n't know who he 's working for .
