Gail Peck
家庭壓力及工作上的不幸對Gail Peck來說並不是一件新鮮事。當她的同僚知道她來自警察世家時，她就算抵擋得住這些刻板印象，卻逃不過任人唯親的嫌疑。今年Gail面臨的壓力會更加嚴峻。她將會面對母親在她工作崗位上的出現、她與同儕間的關係轉變、不公平的指控，以及揮之不去的問題—究竟她想從工作上得到甚麼？她是否命中注定是個惹人厭或成為笑柄？
Family pressure and professional mishaps are nothing new to Gail Peck. She weathered the storm when her colleagues learned about her cop-royalty lineage, but she still can’t escape suspicions of nepotism. She’s bonded with her fellow rookies – but that doesn’t mean she’s not still out for number one. This year, the tension for Gail will be kicked up a notch. With her defense mechanisms firmly in place, Gail will face her mother’s presence in her workplace, her own changing relationships with her peers, unfair accusations -- and lingering questions about what she really wants out of the job.
Chris Diaz
Chris已經適應在大城市維持治安，不再是那個來自Timmins的天真警察。他仍然渴望逮捕壞人及做好事，但事實並非容易。生活上的衝擊在今年裡接踵而來。他將要決定「正確的事」是代表什麼。正如他們所言，好心做壞事。更糟的是，他與好友Dov及女友Gail Peck的關係將會受到前所未有的考驗。
Chris Diaz is no longer the wide-eyed rookie from Timmins. This year, life attacks from all angles. Chris survived a difficult childhood and put it behind him – but that doesn’t mean it won’t rear its ugly head. Ethical choices will force this good guy to decide what exactly ‘the right thing’ means; and his good intentions will land him in hot water. Worst of all, his relationships with best friend Dov and girlfriend Gail will be tested like never before.
Dov Epstein
Dov Epstein最終脫離了隊伍，嘗試靠著自己的能力成為一名主要警官。但Dov對於成為好警察的渴望卻令他在工作上變得不計後果。他開始明白不是所有罪案都能夠解決，受害者也未必願意接受幫忙。他也開始明白到要成為一名警官，就要接受工作上不能改變的事情。Dov仍然與他的好友Chris Diaz同住。當Chris的女友Gail Peck (Dov的長期敵人)搬過來和他們同住時，Dov無法控制對她的敵意。
As Dov starts to learn that not every crime can be solved he’s also starting to realise that part of growing as an officer is accepting the things about the job that you can’t change. Dov still lives with his best friend and wingman Chris Diaz. And when Gail, Chris’s girlfriend and Dov’s long-time enemy, moves in with the boys, Dov can’t contain his animosity for her. But as Dov starts to see the world of policing through more mature eyes, he also starts to see those closest to him differently too – specifically Gail.
Traci Nash
第一眼看Traci完全不像一名新警員。身為7歲兒子Leo的母親，Traci從不輕言放棄。不幸的是，當要與你的舊情人一起工作時，生活就不是如此簡單。剛開始幾個月嘗過文書工作後，Traci又重新回到街頭工作。當該區一名新的探員察覺到她的天賦時，她終於感到自己得到應得的認同。但當你發現自己的好友和良師不和時，你又會怎樣做呢？
Traci Nash is not a woman who gives up easily, and setting up house with her son’s baby daddy just seemed like the right thing to do for everyone. Unfortunately, life just isn’t that simple when you’re working with your ex-flame. As Traci works to hone her skills as a policewoman, she’ll figure out what she really wants from her life and from her job.
Andy McNally
Andy McNally是一個處於充滿危險性及戲劇性的世界中的新警員。警校訓練結束後，她已準備好迎接朝她而來的新挑戰。但本季她將發現工作以外的混亂也難以逃避。無論她是喬裝、制伏罪犯，還是與連環殺手面對面交涉，她發現愈快找出如何處理突發狀況愈好。本季是Andy在情路上及工作上的混亂期。無論哪樁都是一件危險的事情。
After prevailing through the rougher patches of her first year as a rookie officer, Andy is ready to step up and tackle any challenge coming her way. She is in a seemingly perfect and un-complicated relationship with Homicide Detective Luke Callaghan and she’s finally put aside the undeniable chemistry she’s got going with Training Officer Sam Swarek. For once, she’s chosen with her head, not her heart.
