Season 1

Tired of being passed over for promotion at her law firm, Joanna Hanley returns to her hometown to defend a drug company.

A fish out of water in a town that's as foreign as it is familiar, Joanna battles with questions over her family's hasty departure when she was a teenager and attempts to convince the locals that she has in fact switched sides.

Joanna uses her esteem as partner at CTS to convince a hydrologist to test Millwood's soil. With reluctant permission from the mayor, Joanna and Billy narrow their list of suspects to a handful of industrial sites in the community.

Joanna and Billy are convinced that the local steel mill and its owner Ben Matheson are responsible for the barrels. A shocking revelation in Joanna's personal life leads her to question everything her father had told her.

The sick girls and their families are faced with the mill employees who are worried about losing their jobs.

As threats against her and Billy escalate, Joanna hopes that a neuropsychologist will prove that the girls were poisoned.

Stuck in Millwood without a case and no firm to return to, Joanna is at loose ends on what to do next until a whistleblower comes forward.

New leads bring Joanna and Billy to make the horrific discovery of a massive dumpsite on farmland near the school. Joanna’s father takes over as lead counsel and it becomes clear that they’re running out of time.

Joanna faces the one person who can help her defeat her father.

After being reinstated, Joanna plays her trump card, but it's not enough to elicit a settlement.
