Things are still tense between Walker and Liam after Liam called in a false warrant on Dan Miller. However, things take a turn for the worse when Captain James informs the brothers that Serano’s lawyers are using Liam’s mistake as a way to set the criminal free, putting the entire Walker family in danger.
