Our girls are back.

The trailer for the highly anticipated second season of the hugely popular Netflix series Firefly Lane is here, and it has us more excited than ever. The show is based on Kristin Hannah's novel of the same name, and it follows Tully Hart (Katherine Heigl) and Kate Mularkey (Sarah Chalke) both in the present day, and through flashbacks to their younger selves. Throughout the show, the audience is tasked with piecing together the puzzle that eventually led to the end of their friendship. In the last season, we see Tully in her role as a beloved daytime TV host, while her pal Kate attempts to get back into the workforce while navigating a divorce. In the trailer, we see Kate care for her ex-husband amid his recovery after being injured in the Middle East. Despite their sticky situation, it's clear the two have unfinished business which is bound to be explored in the upcoming season. Tully, meanwhile, has her fair share of professional and personal difficulties. After being ousted from her own show and served legal papers, she decides to head down a different path and start a documentary in order to find her father, while finding her voice – and herself – along the way. The official synopsis from Netflix reads: "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." The new series lands on Netflix on 2 December.
