After an explosion at SF International Airport, Ironside discovers that someone has abandoned a baby in his van. Subsequent events suggest that the child's mother was the intended victim of the bombing, prompting Ironside (Raymond Burr) to use the baby as bait in hopes of locating the mom and persuading her to reveal all the facts of the case. In an amusing plot development, the cantankerous Chief proves to be an ideal babysitter! Two sets of 11-month-old twins were cast as "Officer Bobby" in this episode, which was coscripted by "Michael Shayne" creator Brett Halliday. ~ Hal Erickson, Rovi
