A cop is ambushed and beaten, and the incident raises questions about the cop's partner, an officer who once saved Frank's life. Frank feels compelled to give him the benefit of the doubt; then a life-threatening situation arises.
Frank is on the case when an undercover agent is murdered and the two gang-squad cops handling the investigation insist on keeping her identity secret. Also: a bank robbery serves up more bad luck for Billy.
Two kidnappings occur on the same morning in different neighborhoods; Frank tries to address a social injustice when all available resources are sent to find the child of a wealthy surgeon, while the search for a poor child is grossly understaffed.
Frank defends a judgment call made by two cops to rush an injured child to the hospital instead of waiting for an ambulance when a greedy lawyer persuades the mom that the decision aggravated the child's injuries.
