Attorney Oliver Resor is prosecuting a pilot who was drunk when his plane crashed, killing 45 people; and Sandra Broome is conflicted about prosecuting a black cop charged with assaulting a skinhead.

Sandra prosecutes a drug company that's ""using inner-city babies as lab rats"" to test a measles vaccine; officials unearth the identity of the man who killed Michael's family; Gaffney pursues a relationship with a bond trader; and Oliver learns his father has cancer.

Tony Garufi, the man who had Mike's family murdered, is killed the week before he's scheduled to get a subpoena. Meanwhile, after charges of statutory rape against a popular ballet dancer are dropped in L.A., Sandra decides to prosecute him on a Federal level; and Oliver initiates a case against a tobacco company.

Michael resents having to help an attorney prosecute a man involved in the murder of his family - a case he wanted to handle - so he withholds information; and Oliver is arrested after the tobacco company plants cocaine in his car.

Mrs. Abruzzi gives Michael a tip leading to Iredesco's arrest after learning that her husband's killer also murdered Michael's family; a tobacco-company informant dies after warning Oliver and Jessica of a secret agency that monitors the anti-smoking movement.
