With the absence of Captain Pruitt, Andy and Jack try to navigate how to work together, and a car accident on a rural road puts both the victims and the crew’s lives at risk.

Upon the arrival of Batallion Chief Frankel, Jack begins his first shift as co-captain and continues to butt heads with Andy on leadership styles. Captain Pruitt has a difficult time following doctor’s orders and winds up back at the station to take on administrative duties. Meanwhile, the rest of the team at Station 19 responds to an attic fire at JJ’s apartment building and a call to a pool house party.
