His unconventional victories come at the chagrin of his larger-than-life boss, Mac, who prefers to pull the twelfth juror from the brink of conviction the old-fashioned way, through an artful cross-examination and an impassioned closing argument. But before the dysfunctional duo can rescue their new client, a United States senator, from the jaws of an apparent IRS investigation, a hit-and-run attack rips their law firm apart, putting one person in a hearse and another in a coma.
To find the killer, Hank must defend the senator by himself in a criminal investigation that is spiraling out of control.
