It's been a little more than a year since gang unit officer D Araujo found himself staring at the wrong end of a gun at close range on a chase for a suspect. He made it out, but the experience has stuck with him, particularly on cases like the one he's on now - teaming up with the SWAT team to capture a suspect who's been involved in a series of gun battles in Mattapan. Meanwhile, over on the fugitive unit, Greg Dankers works days tracking down criminals while his wife Nancy, also a cop, works nights. With twin boys at home, that doesn't leave many openings for date nights, but as he pursues a suspect, he's hoping there will be enough time to cook his wife dinner after the catch. And for patrol officer Jenn Penton, the ongoing events with her troubled sister is a reminder of how much family matters.
