It's a double whammy at dispatch when St. Patrick's Day falls on a Full Moon. Charline takes matters into her own hands when she hears a couple screaming over an open line, and the night shift tries to track down a man who reports he's been shot.

Rookie Steve Schieferstein is new to CVD but brings a wealth of experience as a former EMT in police officer; for 12 hours straight, Steve must adjust to the other side of the phone and handle all types of calls — from roadkill to a full arrest.

The shift is showered with food and fun during Appreciation Week, but the calls keep coming, including a robbery in real time and reports from the gruesome scene of an accident; dispatcher Tiffany Ward wins an award for a call from the previous year.

As Dispatch Week winds down, Essence keeps her eye on the prize; Charline and Melanie help a caller track down a cat burglar; dispatcher Jennifer Barber struggles to get a caller to start CPR before it's too late, earning herself a lifesaver pin.

Dispatcher Arnold Rinas taps into his 15 years of experience to prepare the new trainees for the job; he helps newbie Salena Hall navigate 911 and must deescalate a dangerous dispute when a neighbor pulls a gun on the caller and her family.

Jennifer Barber is thriving in her first year dispatching at CVD, but when she gets caught in a never-ending cycle of calls involving children, she must lean on her team to help every caller.

When the dispatchers discover the last day of Police Week falls on Friday the 13th, some embrace the strange, while others struggle to find the humor through a shift of bizarre calls involving snakes, surfers and an unexpected seizure.

With only 24 hours to go before Memorial Day finally ends, Charline and the team's determination is put to the ultimate test after days of life-and-death emergencies; it all comes to a head when an officer chasing a suspect goes silent.

With July 4th just around the corner, the dispatchers brace for nonstop complaints and hope for the best. When a block party breaks out in a fight, the dispatchers scramble to get the officers the details they need before it turns deadly.

It's rookie Savannah's first time dispatching July fourth. While she leans on her team's years of experience, there’s no telling what's to come. When a drunk driver takes off on Savannah's officers, she must come to grips with a tragic outcome.
