The 118 fights an apartment building blaze and attempts a daring rescue of a blind woman trapped inside. When Athena responds to a simple accident call, she discovers a potentially more sinister crime. Meanwhile, Hen performs a risky medical procedure after an accident at a televised cooking show and Buck meets a retired firefighter and is inspired to reunite him with his lost love. 
Hen and Chimney mention that their previous crew before Bobby, Eddie, and Buck came were not really considered their "family", a callback to the struggles they faced back in "Chimney Begins" and "Hen Begins".
Tommy Kinard is mentioned by Chimney, on the fact that he needed a favor.
Hen mentions Evelyn, the cello player she had accidentally killed after she crashed into her in "Malfunction".
Parts of the jump that Buck did into the apartment was filmed partly on stage and partly on location. 
The synopsis of this episode says they attempt a daring rescue of a blind woman, although Maddie mentions to the team that she is deaf.
