Netflix’s Firefly Lane is back for a second and final season. The series follows two childhood friends in their adult lives, with flashbacks to their life as teens in the 1970s and the early days of their careers. Tully (Katherine Heigl) and Kate (Sarah Chalke) have been through everything together, so what causes them to fall apart? Audiences will find out this season.

Variety confirmed that the series was renewed for a second season in May 2021. The streamer announced in October that the second season, containing more episodes than the first, would be the last. Firefly Lane was created by Maggie Friedman, writer of Witches of East End and Dawson’s Creek.

Here’s everything we know about the final season of Firefly Lane.

Firefly Lane Season 2: The Plot

Season 1 ended on a cliffhanger, with Johnny (Ben Lawson) injured by an IED while covering the war in Iraq. Tully quits her show and decides to make a new show, asking Kate to come on as a producer. She’s determined to make a better show with her best friend.

However, it’s revealed in the final moments at Kate’s father Bud’s (Paul McGillion) funeral that something happened between the two. It looks like Tully did something that Kate can’t forgive, not even allowing her friend to attend the funeral service.

Netflix has provided a detailed synopsis of what fans can expect in the final season:

Based on the trailer, it looks like Tully’s next move is to film a documentary on finding her father. Instead of allowing someone to take her voice away, she’s making it her own. It seems like something on that journey will tear the two friends apart. The trailer also shows Tully and Kate running away at one point. This may be after Tully is sent to live with her grandma, the two potentially deciding to leave so they could still be close to one another and not separated.

What could possibly have ended the tight-knit thirty year friendship of Tully and Kate, our “Firefly Lane Girls Forever”? We’ll learn the answer this season – but first – Kate grapples with the painful aftermath of Johnny’s ill-fated trip to Iraq, while Tully faces a lawsuit after walking away from her talk show, and must start her career over from the bottom. This leads her to search for answers about who she is and where she comes from – including a quest to find the father she never met, against the wishes of her secretive hippie mother, Cloud.

In the ’80s, we see Kate and Johnny first fall in love, creating more than a little drama in the newsroom where they work, as Tully’s career rises and she spars (and flirts!) with cocky sportscaster Danny Diaz. She just might have met her match – that is, if they can stop arguing for five minutes.

While in the ’70s, teenage Kate and Tully struggle to keep their friendship together as Cloud goes to jail for dealing drugs and Tully goes to live with her grandmother, far away from Firefly Lane. As the girls face the tumult of high school apart, they know the one thing they really need is each other.

Firefly Lane Season 2: The Cast

     Netflix

Katherine Heigl is returning in her role of Tully Hart, and Sarah Chalke is back as Kate Mularkey. Heigl is known for her television work in Grey’s Anatomy and Roswell, alongside romantic comedies like 27 Dresses. Chalke is recognizable from Scrubs, How I Met Your Mother, and Rick and Morty. Ali Skovbye and Roan Curtis will return as teenage Tully and Kate, respectively, in flashbacks sequences.

New cast members for the second season include Ignacio Serricchio (Lost in Space, Bones) as Danny Diaz, Greg Germann (Grey’s Anatomy) as Benedict Binswanger, India de Beaufort (One Day at a Time) as Charlotte, Jolene Purdy (WandaVision, Under the Dome) as Justine Jordan, and Chris McNally (When Calls the Heart) as Mr. Waverly.

Release Date

The second and final season will be split into two halves. The first nine episodes will be available starting December 2. The remaining seven will be available sometime in 2023, though the month or date has yet to be announced.

Everything Else We Know

The series is based on a book of the same name by Kristin Hannah. It is a historical, coming-of-age story following Kate and Tully over the span of 30 years. The event that pulls the two of them apart in the source material is described as “a single act of betrayal,” which doesn’t really hint at what it could be. Looking further into the plot gives a better picture.

On Tully’s show The Girlfriend Hour, she brings Kate and her daughter Marah out. Kate isn’t told what the segment is for. It turns out it’s about overprotective mothers, so Kate feels used and betrayed by her friend for putting a label on her relationship with her child on national television. If the adaptation is to follow in the same footsteps, fans will see Tully somehow get her show back over the span of sixteen episodes just so she can tear her friend down for views.
