In trying to find an alternate theory to Larry throwing his wife through the window, Josh and his team discover another man's DNA in the bedroom, possibly leading to another suspect. Meanwhile, Josh is concerned about Larry's lack of emotion about the murder and his strange obsession with a skate wrench.

With the trial now getting national attention, Josh's boss, Mr. Mankiewicz has decided to take over the case, throwing the team into turmoil. Meanwhile, when Mankiewicz suggests Larry plead insanity, Josh and Carol Anne Keane must work together to convince Larry to stand trial.

After the prosecution presents its case for 28 grueling days, Josh's defense suffers a major setback when Summer turns into a suspect. When Larry forbids Josh from putting Summer on the stand, Josh must decide how much he's willing to sacrifice to get Larry his freedom.

As Josh focuses on making his final case before closing arguments, he takes a huge gamble by putting Larry on the stand. Despite hiring the best witness coach in the South to train him, Larry's testimony leads to a shocking discovery about Larry's past that may be too difficult to overcome.

The trial is over and the verdict is finally announced. A key piece of evidence is found that answers the question, "Who killed Margaret Henderson".
