10 year-old Maddie Harrington shows up on Ally's door saying she's her daughter. She's the result of a mixup on the egg bank Ally deposited her eggs ten years ago. Since Maddie's father died six months ago, she's been living with her aunt, who sings TV themes on nightclubs for a living. After a lot of talking, Maddie decides to stay in Boston with Ally on a trial basis until they resolve where she will stay. Meanwhile, Richard takes the case of a man who killed his wife after kicking her in the head when he mistook her for a soccer ball. John doesn't think he'll be able to win the case because he can't litigate, but Richard surprises him when he wins.
