As the second episode of "Playing Gracie Darling" unfolds, Joni awakes from a haunting nightmare, her mind still reeling from the sight of her late friend's charred bones in the forest. With a renewed sense of purpose, Joni and Jay set out once again into the forest, their hearts heavy with unanswered questions about Gracie's tragic demise. Jay's suspicion of Joni's knowledge of the remains' location simmers beneath the surface, as they delve deeper into the mystery.
Their return to the forest is marked by a discovery: an infinity sign, a symbol that held special meaning between Joni and Gracie. Joni recounts how a young girl resembling Gracie led her to the remains, and Jay urges her to find closure in the face of this unfathomable loss.
In the present, Joni embarks on a journey to find Billy, a man with a penchant for collecting birds who resides on a houseboat. As she engages with him, Joni notices the same infinity sign that had previously held significance for her and Gracie, now etched onto a board in Billy's cabin.
Back home, Joni is reunited with her mother Mina and daughter Lulu, while Bob's cordiality towards Pattie hints at the complexities of their relationship. A flashback shows Joni meeting Gracie, seeking refuge from her parents' tumultuous arguments. Gracie's evasive response about a bruise on her thigh only fuels Joni's curiosity about her friend's private life.
In the present, Joni takes Lulu to the Darling household, seeking answers from Moira and Ruth about Gracie and Frankie's disappearance. Her questions are met with defensiveness from Ruth, and she turns to Jay for reassurance that Gracie may have been in a relationship with an abusive partner. Jay's lack of knowledge only adds to the mounting sense of unease.
Meanwhile, Raffy and Mina discuss Frankie's fate amidst a prayer session organized by Caitlyn, a member of their youth group. Raffy's assertion that Frankie hated Caitlyn is met with Mina's insistence that they attend the session, adding another layer of emotional complexity to the already tangled web of their lives.
As Joni gently lulls Lulu into slumber, she assures her that Mina will not be taken away. She confides with Lulu's parents about Mina and Raffy's latest escapades, their bond deepening with each other's company. Meanwhile, Jay converses with Billy, his brow furrowed in concern as he inquires about Gracie's romantic entanglements at the time of her demise.
That night, Joni turns on the mixtape, her heart pounding as she listens to a recording from the night before Gracie disappeared. Jay, Anita, Joni, and Gracie are gathered at the cabin, summoning Levi's spirit. Jay's skepticism persists, but as the spirit spells out Joni's name in the air, terror grips them all.
Elsewhere, Raffy and Mina find themselves at the prayer meeting that unexpectedly turns into a rave. Under the influence of drugs, they watch in fascination as Caitlyn invites a group of teens to play 'Gracie Darling.' Suddenly, Caitlyn is possessed by Gracie's spirit, her body convulsing in uncontrollable fits. One of the girls asks about Frankie, and Caitlyn and the others collapse to the ground in a synchronized seizure.
At the hospital, Jay and Joni discuss the mysterious seizures among teenagers in the forest. Joni interrogates a nurse, who reveals that not all the affected teenagers were under the influence of drugs. Back home, Mina tries to alert Joni about something she sees in the woods, but Joni dismisses her concerns. She sends Mina to bed, her mind racing with thoughts about what happened in the forest.
A flashback transports us to the beach where Joni and Gracie are enjoying their time until Billy shows up with an offer of alcohol. Billy tries to share a drink with them, but Gracie's abrupt rejection and subsequent swimming away leaves Joni stunned by her friend's behavior. The present-day Joni is now in the shower, her eyes closed but visions of Gracie and the infinity symbol haunting her as the episode draws to a close.
