Katrina is involved in the case, as part of a car crash right next to headquarters. A young mom is facing immigration problems and our heroine goes to bat for her, taking her young American-born son temporarily under her care, while the mother is in jeopardy -undocumented. Comically, Law is called "Wonder Woman" for her quick action after the accident.
Soon, the woman disappears from the hospital and the plot thickens. Main subplot involves Katrina's relationship o the young boy under her care -she's ill-equipped to handle a yonter,but the team helps out. Rest of the show i standard police procedural action. Scott Lawrence plays the DEA agent who wars wih Cole in trying to take over the case from NCIS, since technically it has nothing directly to do with navy matters.
