‘9-1-1’ Season 3 Premiere Spoilers: Episode 1 Synopsis, Cast, Preview Trailer

Fox’s first responder drama, “9-1-1,” is back with its Season 3 premiere on Monday, and it’s bringing another natural disaster along with it.

While Season 2 kicked things off with an earthquake, this season debuts with a tsunami hitting Los Angeles that’ll “make [the] earthquake look tame in comparison,” showrunner Tim Minear told TVLine.

Last time around, all of the main players survived the catastrophe, but, this time, Minear teased to TV Insider, “Some will live; some will not.” Who won’t make it out of the disaster alive? Fans won’t find out for a little while as the tsunami storyline will last a few episodes.

Along with water invading Los Angeles, what else can “9-1-1” fans expect to see happen in episode 1, titled “Kids Today”?

“Athena [Angela Bassett] enlists the 118’s help when a teenager speeds out of control on the freeway,” the synopsis shares. “Meanwhile, a routine traffic stop uncovers a shocking kidnapping and Buck [Oliver Stark] struggles with his recovery.”

The “9-1-1” Season 3 cast also includes Peter Krause (Bobby), Aisha Hinds (Hen), Kenneth Choi (Chimney), Jennifer Love Hewitt (Maddie) and Ryan Guzman (Eddie).

Plus, Gavin McHugh (Christopher), Bryan Safi (Josh), Tracie Thoms (Karen) reprise their roles for the episode, while Terryn Westbrook (“Law & Order True Crime”) and Dash McCloud guest star.

“9-1-1” Season 3 premieres on Fox on Monday at 8 p.m. EDT.
