Ambitious young cops try to prove themselves in their high-stakes careers, in which the smallest mistake can have deadly consequences. At the core of the close-knit group is perfectionist Andy McNally (Missy Peregrym), whose father was a homicide detective before he burned out on the job. The series follows Andy and her four colleagues -- Dov Epstein, Gail Peck, Traci Nash and Chris Diaz -- as they experience the trials, triumphs and tribulations of police work, as well as its effect on their personal lives.

A robbery on a casino-bound bus filled with seniors threatens Frank and Noelle's wedding; Traci loses Noelle; Andy and Nick share an intimate moment.

The squad searches for Chris' son Christian after he is kidnapped.

A routine drug bust turns into Traci's first murder case; Swarek, Oliver, Chris and Dov spend a weekend at Oliver's cabin; Andy and Sam both have confessions to make.

Andy finds out Marlo has been carrying out an unauthorized investigation into a pedophile; the drug sweep Traci is overseeing takes an unexpected turn when Sam leaves to help Marlo.
