Back on active duty, Bobby Simone (Jimmy Smits) reteams with Andy Sipowicz (Dennis Franz) to investigate a bar shooting. The suspect, an off-duty corrections officer, turns out to be terminally ill, and may not have been responsible for his actions. In another development, the squad converges upon the hideout of a serial rapist. And although she hasn't formally announced her pregnancy, Gina (Lourdes Benedicto) accepts Martinez' (Nicholas Turturro) marriage proposal. ~ Hal Erickson, Rovi
