It takes a team of people to help answer the famous question, "911, what's your emergency?" Detective Athena Grant works as a member of the police force, handling cases that require her sharp mind and expertise, while also trying to juggle her own family drama. Bobby Nash and his team of firefighters help execute the daring rescues that often come along with these life-threatening situations. Meanwhile, Abby Clark spends her days taking and fielding emergency calls at the 911 call center, but constantly desires to know what happens after she sends help.

The crew races to an emergency when disaster strikes at an Indian wedding. Abby enlists the help of Buck to try and find her mother and, for the first time, meets Athena face-to-face. Meanwhile, Bobby has a difficult time confronting his past and Hen struggles to make the right decision.

What goes around comes around for an unremorseful widower, an arrogant fitness club owner and an unsuspecting thief. Meanwhile, Bobby gets a surprising phone call from his doctor after donating at Chimney's blood drive, and Athena confronts Michael after having a heart-to-heart with their kids.

When the first responders race to the rescue of a crashed news copter, they unwittingly become the subject of an eager reporter's first on-air assignment. Meanwhile, Bobby tries to deal with his daughter's death, as Athena prepares for May's homecoming dance. Then, Maddie struggles to let go of her fear of the past. Also, the team responds to emergencies at an eating contest, a bodybuilding competition and a toddler pageant.
