Aspiring audio producer Harriet gets the career boost of a
lifetime: the chance to interview internationally famous thriller writer Lili Novak, who has agreed to give a masterclass about
her creative process. The dream gig takes a dark turn, however,
as Lili immediately dives into an eerie recount of her childhood. In stories about the dangerous tenement she grew up in, Lili reveals the friendships she formed and the disturbing experiences
they all endured together—some of which still haunt her.

Captivated by the tales and obsessed with the prospect of
being the one to tell Lili's story to the rest of the world, Harriet ignores the red flags signaling the novelist may not be in her
right mind... or that something even more sinister is happening.

Created by Aditi Brennan Kapil and unfolding over six episodes, Marrow is a harrowing psychological thriller that asks: Is anyone ever really who they say they are? As Lili’s tale unearths winding paths of trauma, lies, and deceit, to a shattering revelation, Harriet’s dream will be completely—and irrevocably—shattered.
