Why Season 16 Could Become A Landmark Chapter

After years of earthquakes, floods, fires, and explosions, Season 16 would offer something different: a battle against a threat created by human choices.

Most importantly, the season would remind viewers why 9-1-1 continues to resonate after so many years.

Because no matter how complicated the crisis becomes, the heroes of the 118 never stop fighting for the people who need them.

And in Season 16, that fight could become the biggest one of their lives.
