After Seth learns that the people of his hometown and former elementary school in Lincoln, Nebraska, have become seriously ill due to groundwater contamination, he becomes invested in seeking justice, potentially jeopardizing the future of his career. Sandra, Jay and Allison assist Jill with a potential murder case, but as they grow skeptical of their client, Jill only grows more passionate.

Sandra defends a hydrologist accused of spying for the Chinese government, but the similarities between this and a former case she lost has her confidence shaken. Meanwhile, Jay faces his fears and goes up against Kate in a case involving a PTA president accused of selling drugs to students; and Allison receives a tempting proposition from her wine-forger client and Leonard reaches out to Kate for advice that culminates with a surprising confession.

Sandra urges Kate to take on a case against a very powerful and well-respected judge who is accused of wrongfully sentencing young children for profit. When Judge Bryne is asked to testify in the case, he questions his role in the rigid justice system and must make a very difficult decision. Elsewhere, Seth temporarily moves in with Jay until a leak in his apartment is fixed.

On Election Day, Jay turns to Kate and the team for help after his parents and other voters are illegally intimidated at their polling place. Meanwhile, Roger and Jill’s relationship is at an impasse when Sandra learns that they are romantically involved and challenges Jill’s judgement. Elsewhere, Seth gets assigned to the case of a lifetime, but his anxiety increases when he is appointed a bodyguard to help protect him, all while Sandra and Ted take their relationship up a notch.
