The Firefly Lane Season 2 Trailer Dives Deeper Into Kate & Tully's Lifelong Friendship

Kate (Sarah Chalke) and Tully (Katherine Heigl) are going through some serious stuff in the trailer for Firefly Lane's final season. 

From legal battles and romantic entanglements to unexpected drama and family secrets, Firefly Lane Season 2 will see these best friends navigate just about everything life has to offer. As we experience the BFFs' journeys at present, we'll also jump back in time to the '70s and '80s, where high school and burgeoning careers shape the women and their friendship. While it may seem like these ladies are in it for the long haul, the trailer also hints that a dramatic event may put an end to the 30-year friendship that has kept them afloat since they were teenagers. 

In addition to Heigl and Chalke, Firefly Lane stars Ben Lawson, Beau Garrett, Ali Skovbye, Roan Curtis, and Yael Yurman. This season, India de Beaufort, Greg Germann, Jolene Purdy, and Ignacio Serricchio will join in new roles. The series, based on the novel of the same name by Kristin Hannah, stars Heigl and Chalke as unlikely BFFs Tully and Kate, two women whose 30-year bond endures ups, downs, and everything in between over decades of friendship.

Netflix announced last month that the series would end with a super-sized second season. The first half will drop in December, while the final installments will arrive in 2023.

Firefly Lane Season 2 debuts on Netflix December 2 with its first nine episodes. The first season is currently streaming.
