LaSalle has a chance to move out of the precinct and into a more regular routine of detective work. A thirteen-year-old boy is shot. Sipowicz suspects a private investigator of bilking a father, for the past six months, in a scheme to find the man's daughter. Andy's also was looking for her for the past 2 1/2 years. The father of the murdered boy apprehends the killer, after he discovers the killer (whose injured LaSalle) has escaped from the precinct.
