The Good, the Bad, and the Nasty - S1.E5

A group disguised as the Boys hits a crack house leaving ten bodies in the wake and the Nasty boys locked in the sights of Internal Affairs. With the police brass breathing down his neck Krieger refuses to divulge the names of the Nasty Boys. It is not long before the mastermind behind the Nasty Boy's problems is revealed as an old enemy, Payday, last seen in the pilot movie. Payday killed the Boys first leader and now the Boys are out for a little payback.
