Noah comes to see Benson. The babysitter has to go home and take care of her husband's migraine.

Muncy is working late, trying to find a peeping tom. Benson advises her to get it right before she goes to court.

Meanwhile, an Indian girl doesn't like her father trying to fix something. The father finds her disrespectful. The mother says it is America.

Muncy and Valesco are in a store looking for clothes. Muncy reveals she is colorblind. Valesco is impatient to go.

The Indian father sees a man come into his store. The man has a gun. The wife is in the shower and tries to call 911. The gunman comes in.

Muncy and Valesco are called to the case. The husband and wife have been shot and the wife possibly raped. Valesco doesn't think this is a rape. Muncy discovers there is a teen daughter. Velasco thinks that the birth control pills in Pria's desk means that she got her boyfriend to shoot her parents. Muncy doesn't think so. Anyway Pria's phone is still here so she was likely kidnapped.

Benson compliments Muncy on her clothing today before going to talk to the mother. The gunman was searching for Pria and wore boots. Her husband fired a contractor recently and was doing all the work himself.

The contractor says Raj was a prick who claimed a day laborer was looking at his daughter. Sure enough, that's who the gunman is. The cops cannot find him. Somehow Muncy finds out.

The cops don vests and head upstate to find the perp. They find a dollhouse outside and break into the house. It's empty but Benson finds a padlocked door leading to a secret room. Pria is found, along with two other kids.

One of the victims, Nadine, says she isn't supposed to leave. The police reassure her she won't be hurt anymore. She is taken to the ambulance. Benson says they have to find out who these kids are. Muncy says one of the little girls is calling another one Mommy.

The neighbors know nothing about Elias. He's in the wind and could be anywhere. Benson orders everyone not to talk to the press before talking to her.

The girls are identified. Many of them disappeared years ago. Nadine is three months pregnant and Bella might be Julia's child. Benson sends Muncy to talk to Pria.

Muncy talks to Pria and reassures her that her parents are okay. Muncy is gentle and empathetic and gets the story out of Pria.

Nadine IDs Elias and then freaks out. She says that Elias was in a hurry and told them to teach the new girl the rules. Gillian says that Elias locked them in the basement like he always does when he goes out. She never knew what day or month it was. She starts crying and scares Bella.

Nadine freaks out and doesn't want to talk anymore.

Pria tells Muncy it was pitch black and she was quiet and he said she was a good girl.

Benson realizes Elias was buying food. She wants an APB at all supermarkets.

Elias is buying ice cream when the cops approach and he tries to run away but Muncy gets him. Fin takes her off him before she hurts him.

Elias says it wasn't him, it was his daddy.

Benson is concerned that Elias having a lump on his head will be a problem. Fin tells her that Muncy beat him up but he's been checked out. Benson says Munchy will have to go in and apologize.

Pria IDs Elias from a photo. .Also her father is awake now.

Muncy is asked to step in to the interrogation. She apologizes for hitting Elias. The interrogation begins. Elias insists he didn't touch that girl. Muncy says she believes him.  He gets violent when Fin says they found him with the keys to the padlock. He says it was his father. He took Pria to make his father proud.  Elias' lawyer claims Elias was abused and coerced.

Observing, Benson wonders if the girls heard something about Soren's road trip,

Gillian says Soren took her, not Elias. Elias is never violent. Soren broke her fingers and her ankles. But he allowed her to keep Bella.

Nadine says Soren raped them but Elias never touched them. Elias was in charge when Soren wasn't there. She doesn't know where Soren went hunting.  She freaks out when a worker tries to close the door.

DNA shows Soren is the father of both Elias and Bella, and he also raped Nadine.

Soren is found dead in some woods. He has been dead at least six weeks and was shot.  There was a second body, skeletal remains of a newborn, a boy who has been dead at least four years. The baby' sburial was respectful.

Elias is shocked that his father is dead. The slug matches Elias' gun. Elias claims he would never hurt his daddy. One of the girls must have got in his room. He begins crying.

Duchess County DA wants an update on the case. Rollins realizes Elias is too tall and one of the girls shot Elias. Benson doesn't want to put the girls through this but Maxwell insists.

Rollins questions Nadine who says Soren said he had too many mouths to feed and killed her baby.

Gillian says she and Nadine buried the baby but Elias must have killed Soren. Gillian says maybe it was the Indian girl. Benson says the timeline doesn't work. Gillian says it was her. Nadine tells Rollins she did.

Benson says the girls are protecting each other, or somebody else.

Benson talks to Bella, who says good girls aren't supposed to talk.  Benson tells her to nod yes or no to her questions. Benson realizes Bella shot Soren.

Fin comes across Muncy trying to get blood off her uniform. Fin tells her they used to rough guys up all the time. But she needs to think more tacticly. She has to protect herself. What if things went bad and she needed that radio?

Benson tells Maxwell that Soren murdered Nadine's baby two years ago and Nadine is pregnant again. Maxwell guesses this is a stalemate, but an open homicide stays open forever.

Gillian says that she and Bella are going home. Benson says she is there if they need anything. Gillian is scared to leave. Benson encourages her.
