Some friendships never fadeโeven when one of them is gone. In its final, soul-stirring season, Firefly Lane returns to Netflix for a poignant farewell. Katherine Heigl steps back into the role of Tully Hart, now facing the hardest chapter of her life: living without her lifelong best friend, Kate Mularkey. Though Sarah Chalkeโs Kate is gone, her presence is felt deeply through emotional flashbacks and memories that refuse to fade.
Grief becomes the heart of the storyโbut not without hope. As Tully revisits the milestones, missteps, and magic of their friendship, she begins to discover how the past can light the way forward. Their story, once lived together, now becomes a guide for Tully as she searches for healing, purpose, and the strength to keep going.

Filmed with striking beauty using Canon cinema lenses and backed by a $50 million production budget, The Final Chapter is a visual and emotional triumph. Each frame reflects the tenderness of memory and the aching realism of letting go, bringing added depth to a story that has always thrived on raw honesty and heart.


Tullyโs journey is more than mourningโitโs transformation. As she steps into a new phase of life, she reconnects with those around her, makes peace with the past, and ultimately learns that the love she shared with Kate still shapes the person she is becoming. Their friendship, even in absence, endures.


Airing in 2025, Firefly Lane: The Final Chapter stands as one of Netflixโs most anticipated goodbyes. More than a conclusion, itโs a tribute to lifelong friendshipโone that promises to leave fans with tears, closure, and a reminder that some bonds never break, no matter how the story ends.
