Joanna and Billy face a verdict in their first case in their new firm, but when they return to Millwood for a high school reunion, an old friend from Joanna's past suffers a devastating loss that forces Joanna to face long-buried demons from her past.

Reeling from the sudden apprehension of Kodie's children by Millwood Family Services, Joanna sets out to win back custody, but in order to win in court, she must conduct a thorough and potentially revealing investigation into her old friend's life.

After losing at the custody hearing, Joanna is desperate to help Kodie and recklessly launches an emergency challenge to the court-appointed custodian. The case brings Billy face to face with the last person he wanted to see.

Kodie snatches her kids and goes on the run. With Millwood Police looking for her and with the imminent threat of a province-wide Amber Alert, Joanna must track Kodie down to have any chance at saving her custody case.

With more potential cases of wrongful child apprehensions, Joanna and Billy investigate Millwood Family Services and discover a potential error in the custody hearing evidence that will change everything in the case and in their lives.

In an attempt to build a case against ClearDawn labs for the wrongful apprehension of children in Millwood, Joanna reluctantly agrees to try to put together a class-action lawsuit. Billy gets a tip from his father about a potential break in the case.

Coming off the loss of class certification, Joanna and Billy decide to go after ClearDawn alone with an unreliable whistleblower as their only lead. Luna goes to extreme lengths to save another child from a wrongful apprehension.

Joanna and Billy head to trial against ClearDawn labs while still desperately searching for a way to expose the fraudulent science used to wrongfully apprehend children.
