Plot summary
Lightman is called upon by a prosecutor to testify as an expert witness in the trial of a beautiful widow accused of murder. The widow is accused of murdering her much older billionaire husband. She is also accused of having an affair with her step-son and stealing from her husband's company. It is a national case that pits Lightman, working for the prosecution, against his ex-wife, who is the defense attorney in the case. Foster, meanwhile, coaches the prosecution witnesses on how to behave on the stand, and how to engage the jury. Loker and Torres discuss her involvement with an older person.
