Boston's Finest

After a stint in Afghanistan, Officer Jenn Penton patrols Boston with a rare intensity and sense of purpose - particularly when it comes to getting drugs off the street.

The officers of the Boston Police Department live in the city they are dedicated to protecting, working to balance fighting crime with finding time for family. For the department's Gang Unit, the target is a well-known figure whose capture becomes personal. Meanwhile, the Fugitive Unit cases the streets of Charlestown for a local suspect wanted on charges in New Hampshire. And on-duty Patrol Officers drive through the city streets, encountering an assortment of characters and challenges on every shift.

The Boston Police conduct a massive drug raid in South Boston, and a patrol officer looking for love experiments with speed dating.

In Dorchester, a string of gang-related shootings has the Boston Police Department on high alert. Things take a turn for the worse when a 20-year-old apparent gang member is shot execution-style in a local barbershop. With retaliation expected, the cops do everything they can to calm tensions and prevent another tragedy. Across town, the Fugitive Unit is on the trail of a dangerous knife-wielding robbery suspect.

After more than a quarter century as a Boston cop, and following a year filled with personal difficulties, Robert "Twitch" Twitchell has gotten a call: He's being promoted to Sergeant. Now, with just a week left as a detective on the gang unit, he's focused on bringing in one last criminal, a gang member wanted for assault with a firearm. Leading the search for the suspect, though, will require every bit of wisdom and experience he's acquired on the job. Meanwhile, on the night gang unit, it's a very different kind of week for Officer Myles Lawton, as the anniversary of the murder of his father, a former cop himself, is approaching. The emotions are complicated by a frustrating case in Roxbury, where a shooter got away, and no one seems to know anything about him.

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.

Terrique Chambers didn't become a Boston police officer because it was an easy job, but after six years on the force, his work is - more than ever - at odds with his family life, and his responsibilities at home. With two young sons, one of whom is autistic, the challenges of working nights in the gang unit are mounting. Meanwhile, his counterparts on the day gang unit are focused on something very different: the Boston Police Department's annual fitness challenge, and their desire to outperform their rivals in the fugitive unit. But Ryan Mason, Greg Dankers and company have a secret weapon in the competition, and they'll get an additional boost of momentum if they can first track down a dangerous criminal said to be hiding out in Dorchester.

As a patrol officer, Jenn Penton is constantly facing new challenges - with every traffic stop, every call, every assignment. She's called upon to solve problem after problem, day after day, and is one of the department's best. But her family has shown her that life doesn't always present issues that can be solved in short order. Her twin sister Melissa has been battling addiction problems for years, and after a few recent setbacks, has reached back out to Jenn - maybe for the last time - for help. On the fugitive unit, meanwhile, Winston DeLeon and company are pursuing a suspect from a rape case dating back to 1992. DNA testing matched the guy back to the crime, and now the Boston Police has to find him. And Manny Canuto and D Araujo of the gang unit find themselves assisting in another SWAT raid, continuing their unrelenting quest to get as many guns off the streets as possible.
