Worried about the well-being of his son Theo, Andy (Dennis Franz) considers remarrying his ex-wife Katie (Debra Monk). After breaking up with Mary (Sheeri Rappaport) for good, Danny (Rick Schroder) dedicates himself to keeping Diane (Kim Delaney) out of harm's way -- which Diane deeply resents. And a New York police captain (Richard Brooks), the husband of a woman cop wounded in a shoot-out, endangers the successful prosecution of the case by beating up the suspect. Garcelle Beauvais-Nilon makes her first appearance as new Assistant DA Valerie Heywood. ~ Hal Erickson, Rovi
