Everyone is less than enthusiastic when Sullivan assigns each member of the crew a specialty skill to learn. During a house call, Ryan is caught off guard when he comes face-to-face with someone from his past; and Sullivan, Andy and Maya handle a structure fire in a derelict building.

Just when Ryan agrees to talk it out with his dad, Greg Tanner makes an unexpected visit to Station 19, leaving Ryan and others confused. In an effort to connect with his crew, Captain Sullivan enlists the help of an unlikely source for some bonding tips.

As the team gathers for a Friendsgiving celebration at Dean’s, a violent windstorm touches down in Seattle. As the storm picks up speed, creating dangerous fire conditions, the crew must put the festivities on hold and report for duty, leaving some of them in a life-threatening situation.

In the aftermath of the windstorm, Andy and Sullivan’s fates remain unknown while trapped in the overturned aid car. Meanwhile, back at the station, the team confronts Jack about his well-being; and when it’s safe enough to venture out, they search for their fellow firefighters in a race against time.

When Andy, Maya and Dean respond to a call, they find an injured woman with amnesia; but soon into the treatment process, they realize there is much more to her story. Meanwhile, Captain Sullivan takes Ben and Jack on a house call that quickly becomes a close call for the patient they’re treating, while Ryan may not have seen the last of his father, Greg.
