An ambitious young lawyer joins a high-profile litigator to expose a billionaire's stock market manipulation and ends up as a suspect in a gruesome murder.

After Katie is prepped to testify in the case against Frobisher, Patty suspects she's withholding key information that could undermine her credibility on the witness stand.

As a bomb threat puts Patty and her family on edge, Ellen's loyalty to the firm is tested when she must choose between delivering a brief to an important judge and attending her own engagement party.

Though sure that she's ready to help nail Frobisher, Katie sees that she's been used after the accuracy of her deposition is called into question.

Frobisher (Ted Danson) pushes Ray Fiske (Zeljko Ivanek) to take a more aggressive approach with Patty (Glenn Close), who is on shaky ground with the clients. Tom (Tate Donovan) reckons with his own career options and seeks the advice of an outspoken friend (Donal Logue). Written by: Todd A. Kessler, Glenn Kessler, Daniel Zelman, & Mark Fish. Directed by: Jean de Segonzac.

With the case pushing Ellen and David's relationship to a breaking point, Gregory Malina comes under increasing pressure to testify.
