Rookie Blue

With the impending restructuring of the division, Andy and Sam's wedding comes just in time for the gang to celebrate one last hurrah.

On the day of Steve Peck's hearing, Inspector Jarvis makes a huge announcement. Andy debates leaving town on assignment.

Business at 15 Division is slowly getting back to normal as Alonso Santana and Steve Peck await trial, and as Oliver returns to work as a street cop, back in blue. With the city in the middle of a heat wave, 15 Division opens to the public as a cooling station. After an incident at her mental health facility, a very-pregnant Marlo asks Andy to help track down a patient who she suspects is planning to hurt her ex-husband. But just as Andy and Marlo discover that their missing patient has an entirely different plan in mind, Marlo goes into labor in a high-rise condo with no power. Meanwhile, Dov and Chloe work together to help a local man in the perfect relationship and finally get all their issues out on the table.

With Oliver still the prime suspect in the bombing of 15's evidence room, Andy, Dov, Gail, and Nick plot to prove that Commissioner Alonso Santana is corrupt. Meanwhile Traci shadows Steve Peck, hoping to calm her fears about his involvement in the bombing.

Sam is shocked when Noelle - Juliet's boss at Internal Affairs - tells him that all evidence of corruption at 15 Division points to Oliver Shaw.

When a drive-by shooting occurs during a community-outreach baseball, Gail's relationship with her brother is put to the test.

When Traci fails to show for her first raid, 15 Division is afraid the worst has happened to her.

When Nick's estranged older brother shows up with new information on someone from their past, Nick takes matters into his own hands. When Juliet follows him, Nick is forced to let her into the secrets of his past.

Although Andy is suspicious of the mysterious Juliet, she realizes she'll have to work with her to make it out of the prison.

Andy contemplates her future with Sam after she discovers that Marlo is pregnant with his baby. But Andy's ideas about what makes a perfect family are put into perspective when she meets an out-of-control teen who needs to be protected from her own conservative family.

It's been one month since Ted McDonald's death, the evidence room bombing, and the revelation of Marlo's pregnancy. After a blissful and well-deserved few weeks away at Oliver's cabin, Andy and Sam return home renewed and ready to dig in. But on her first night back, Andy is attacked by an intruder at Traci's house. Andy leaps into action and fights off the attacker; but her shock at the situation compels her to launch her own investigation into what happened.
