The episode begins with a flashback of Brett and Mills in the alley, while they are tending to a patient, two men pull up and kidnap them and tie their hands behind their backs and throw them in a car at gunpoint. They race down the highway and Peter rambles that it wasn’t his fault that Jason Lulo died in the back of the ambulance. The man driving laughs and says that he doesn’t know what Mills is talking about. Mills and Brett attack the men in the car and the driver loses control and crashes that car in to an abandoned lot.
At the station, Casey is trying to track down surveillance footage from the alley. Kelly arrives and says that Boden’s baby isn’t doing well, he is still not absorbing oxygen and the doctors are working on him. Kelly and Casey agree that they shouldn’t worry Boden with Mills and Brett until they figure out what is going on. Herman calls Boden to check in on the baby, and he says that the doctors are still working on him.
Casey calls Dawson to tell her about Mills and Brett, he explains that they are missing and they found the ambulance and it was abandoned. Dawson is sure that Lulo is responsible. Meanwhile, Cruz is out with the police searching for the town car they seen on the surveillance footage. They find where the car drove through the fence and find it crashed in to a barrier. Cruz opens the doors on the car and it is empty, he tells the cop that everyone must have made it out. They learn from the police that the car was reported stolen yesterday. Cruz freaks out that if Lulo has them then they are dead. Cruz is really worried about Brett, he must really like her.
Meanwhile, Brett and Mills are in a warehouse working on one of the men that were in the car. Mills explains that they are just paramedics and if they don’t get him to a hospital he is going to bleed to death. The kidnapper with a gun tells them to fix his friend or he will kill them. Mills makes a deal with the kidnapper with a gun and he agrees to let them go if he saves his friend. Brett argues that there is no way they can do that without the proper equipment but Mills reassures her that they can do it.
Dawson shows up at the scene of the accident and Casey fills her in on Brett and Mills and Boden’s baby. They find some blood in the car and don’t think they could have gotten far. They set up a perimeter and begin looking for them. Meanwhile in the warehouse, Brett and Mills are working on the gunman. Brett tells Mills to clamp his vein in the wrong spot and writes “let him die” in blood on the table. Mills tries to hand Brett the clamp for her to do it but she didn't take it.
Herman shows up at the hospital to check in on Boden and the baby. Boden told him not to keep any secrets from him. He breaks the news to Boden that Brett and Mills are missing and reassures him that Casey and Kelly are all over it. And, the police are investigating. Outside of the warehouse, Dawson finds a trail of alcohol pads that Brett left leading them up to the warehouse, Dawson knows Brett puts a hand full in her pocket before every call. The door to the warehouse is bolted, and they can’t get inside. They hear shots ring out as Brett and Mills make a run for it, into a room. But they realize that they are trapped inside.
The police finally get through the door, and Mills and Brett are rescued safe and sound. Cruz runs and hugs Brett while everyone else hugs Mills. Right away Dawson goes to Mills and hugs him, Casey gets jealous. They all get cleaned up and head to the hospital to check in on Boden. While they are in the waiting room, Casey corners Dawson and explains to her that he is sorry about the other night and explains that he just was charging his phone at the girl from the bar’s house. Boden gives them an update and says that his son is still on a breathing machine.
Brett and Mills are still at the police station, Lulo is being questioned about his involvement in the kidnapping. He insists that he had nothing to do with it and the police have no evidence against him. Mills is furious that there is nothing they can do. Brett and Mills leave and Cruz is waiting outside for Brett. Once they are inside the car, Brett fills Cruz in on the shady guy that she met during the helicopter crash and shows him his business card. She says that he owes her a favor and decides to call him, despite Cruz’s warnings against it.
Cruz and Brett meet up with the shady guy, and she explains to him what happened. She reminds him that he told her if she got in to any trouble he would help her. He agrees and tells her that he will see what he can do.
Casey heads home where Dawson is waiting for him, he tells her there is no change with Donna and Boden’s baby. He sits down and realizes that she has her bags packed and is getting ready to leave. He tells her that they can work it out but she argues that their relationship and job got in the way of each other. Dawson says that they need some space from each other so that they can figure everything out.
At Molly’s Brett corners Mills and tells him that she pulled a few strings and the guy that kidnapped them, Vick, agreed to let Mills come visit him at jail. Mills is baffled and wants to know how she did it but she tells him not to worry about it.
Brett moved out of the bad house in the bad town and Cruz is talking to Otis and was telling him that he is happy that she got a big new apartment and that he now thinks they can have "lazy sundays" together. But then Brett walked over to them and asks if they heard about how Dawson and Casey split up. Then Brett also mentions that Dawson is going to be moving in with her in her new apartment. Cruz is upset with the news.
Kelly returns home and finds Casey trying to fix a hole that he punched in the wall after Dawson left. Kelly argues that he should have fought for Dawson, but he says that he doesn’t want to hold her back. At the hospital a doctor stops by Donna’s room and reveals that the baby is being weened off the oxygen machine and his lungs are improving. However, he is not out of the woods, they have to see if there is any brain damage because he was without oxygen for quite a while.
Mills heads to the hospital to meet with Vick, the man that kidnapped him. Vick says he isn’t going to help him and insists that he doesn’t know Anthony Lulo. He finally admits that he knows Lulo, but then calls for the guard to get Mills out of his room.
At work the next day Mills tells Brett that he seen Vick but it didn’t do any good. Then, she gets her gift the Mills gave her before they were kidnapped. She got a hulu-dancing shark to put on the dashboard of the ambulance. They sit down and talk about how Mills saved Vick, even though Mills told her not to she feels horrible that she actually wanted him to kill a man.
A call comes in for a structure fire and they rush to a storage unit they learn that the smoke is coming from the second floor. They have to find the one where the heat is coming from. Once they break in the door they realize that there is a tank inside that is about to blow. It then blows up, luckily everyone got down in time.
