Episode list

Chaos reigns in the city when Cooper and Lucero are kidnapped and held hostage by a pair of "tweakers" and our cops join the frantic search to find them... before it is too late.

Ben is still confused after his mother's incident and Cooper can't resist exposing his 'rookie failures', yet he manages to star arresting a dazed man by reciting a karate mantra. Sammy is still so frustrated by his unfair divorce that Nate can't rely on him, while Mrs. Morietta feels he's overstaying his welcome, so he'll end up accepting an invitation from fellow ex-husband Sal. They investigate the shooting of Manuel 'Manny' Garces while he's buying a birthday cake for son Rafael. The only decent witness is unwilling to talk. Their likely suspect, small drug dealer Spider, proves dangerous.

In the season finale, John copes with the aftermath of his kidnapping, while Sammy closes in on the real robbers, Ben feels the pressure and Lydia becomes closer with Russell.

On Ben's rookie class's graduation day, Cooper's back-pain and pills addiction not only cause a miserable mood but completely exclude vital backup, so Ben finally forces his ex-tutor to check into rehab. Sammy's son is finally born and Nate's presumed killer 'leprechaun' dies in his arms after a street shooting. He decides to quit desk work and start chaperoning graduated rookies, like Ben. Dewey can't help sparing a blatantly criminal crack whore. Rodrigo is found out being Lydia's lover, making his mother question their partnership.

The body of a dead gang member is discovered; Detective Salinger and his daughter grow further apart; Detective Bryant asks Detective Adams to take in shooting witness Janila.

Ben Sherman finally gets to drive his own patrol car when mentor Cooper acts instead as partner for a female colleague, whose shocking incompetence he demonstrates and scolds mercilessly. Ben is shocked but powerless when he sees a bully father 'punish' his gentle son for being a 'sissy victim' of street rabble by imposing front garden chores in female underwear. Ben smartly questions a Korean couple and their young son Matthew whose sister is missing and learns enough to find her. Cordero told Lydia not to be allover recovering Russell, but she only believes it when his cold reception and other visitor make it obvious.

A documentary film crew accompanies Cooper and Tang on their shift, Ben suspects that Sammy may have planted evidence to help settle a score, and Lydia risks her pregnancy and takes a shift in the field.

John has an eventful shift on the day he receives his pin for 20 years of service, Sammy and Ben try to out-prank each other, and Lydia and Reuben suspect that a father may have killed his 30 year old son.

While detective Sammy Bryant's wife, whose pregnancy proves bogus, works herself into ever more trouble with a skater and marijuana, his detaching to the major drug crime team is canceled by boss Daniel 'Sal' Salinger. Sammy concentrates on acting as big brother for fatherless, smart Latino street kid Juanito, whose cynicism sadly proves justified. Ben and Cooper discover, by searching a rowing couple's home routinely, a drug trade cash fortune, associating them with Nate Moretta's triumph.

Officer John Cooper returns to duty after recovering from back surgery and meets his new partner, Officer Jessica Tang, a tough and disciplined cop with her own set of baggage from working the streets. Lydia, whose new partner is Ruben Robinson, can't seem to escape helping a former CI who won't stay in safety. Ben, Sammy and Dewey chase an armed man into an elementary school, while Ben bumps heads with an intense street cop whose cynical attitude is affecting their work.
