When Danny's brother-in-law suddenly shows up, Danny and Linda take him in despite their reservations. Jimmy tells the kids how their parents used to be hellions and encourages them to drink and play poker, but that's the least of their problems. Thanks to him, there's a car full of mobsters sitting outside the house waiting to beat him up.

Danny finds himself caught in the middle when the mobsters insist they need to settle a score but he wants to keep Jimmy safe. The mobsters insist the only way to settle it is to allow them to beat Jimmy up and tell Danny not to let Linda know about this plan.

While Danny is struggling with this, Nicky is riding along with Jamie. They answer a noise complaint and discover a woman is being abused, but she won't file a complaint against her husband. Nicky is determined to help the woman but all of her actions seem to make things worse.

Frank has a situation of his own to deal with after two cops mistakenly arrest a visiting Latino rock star who is in New York to donate to a program for youth and the star's lawyer takes the department to court to try to get the cops' disciplinary records released.
