The episode kicks off with Detective Inspector Linda Calgetti (portrayed by Gwynne McElveen) meticulously examining the crime scene where Sienna Ryan (played by Joni Morris) met her untimely end. This grim task will ultimately steer her towards the Oxley residence, where Dani (embodied by Kara Tointon) stumbles upon a disheveled Tim (portrayed by Emmett J. Scanlan), nursing a hangover as he slumbers on the couch. Despite the myriad of tensions floating in the air, Dan and Tim find themselves inching towards a reconciliation—until Calgetti storms in, fingers wagging accusations. Tim's haunted visage and his desperate clinging to Dani for an alibi only serve to tighten the knots of tension. However, once they arrive at the precinct, Calgetti unleashes her fury on Dani, accusing her of withholding Sienna's confession.
While Calgetti shifts the blame back onto Tim and proceeds to collect DNA samples, Matt Spenser (brought to life by Forrest Bothwell) learns of Sienna's tragic demise. His return home is swiftly met with Jimmy Spencer's (portrayed by Will Mellor) intense worry, a scenario that benefits neither brother. A fleeting argument later, Matt storms out, severing ties by switching off his phone.
Jimmy, desperate for help in locating Matt, turns to Dani, who in turn seeks the counsel of Chloe Novak (played by Ebby O-Toole-Acheampong). Chloe remains tight-lipped until Dani drops the bombshell of the pregnancy. Chloe's genuine hurt at being kept in the dark is palpable, but a text from Zac Webster (portrayed by Cal O'Driscoll) fuels her suspicion that he had known all along. Not only does Chloe share the incriminating text with Dani, but she also divulges Matt's whereabouts.
Dani and Jimmy track Matt down to a seemingly abandoned indoor swimming pool, its once-glorious surface now marred by a jumble of outdated furniture and random debris. Their brief encounter, though fleeting, speaks volumes. Matt's astonishment and heartache at being oblivious to Sienna's pregnancy are palpable. He confesses to having harbored deep feelings for Sienna and taking the knife, a desperate act to shield Zac from the shame of their affair. Matt maintains a steadfast conviction that he is not the father, a notion Dani concurs with, thanks to the damning text shared by Chloe. Sienna's worries that the father might face incarceration if their relationship came to light now surface, casting a shadow over their intertwined fates.
On an exceptionally rare occasion, Nina Webster, portrayed by Niamh McCann, lets her frustration boil over with Headmaster Robert Caulfield, played by John Nayagam, accusing him of prioritizing his own interests and the school's well-being over the welfare of the students. Meanwhile, Tim, though somewhat expectedly, confronts Dani for not standing firmly with the police, leading to an eventual confession from her: she desires to end their marriage. She voices her sense that Tim is hindering her from becoming the person she truly aspires to be.
In the wake of her separation from Tim, both Jimmy and Matt roll out the red carpet for Dani, showering her with support. Jimmy even goes so far as to offer her the use of the master bedroom, a gesture that may ultimately spell his downfall, as Dani recognizes a floral light fixture from Sienna's artwork. Jimmy, sensing a sudden shift in her demeanor, allows her to leave despite his concerns. Later, at the school, he confronts her, and she confirms her suspicions.
Jimmy strives to justify his actions, but the more he tries, the more Dani's anger escalates. She gradually loses all sympathy for him, taunting him when he threatens suicide with Zac's knife. Following a heated exchange, it comes to light that Zac has discovered Jimmy and Sienna's affair and was poised to expose them. Desperate to protect themselves, Jimmy manipulates Sienna into murdering Zac.
However, Sienna complicates the situation, refusing to give up her child and forcing Jimmy's hand. Eventually, Calgetti is summoned to make the arrest, and Jimmy submits without much resistance. The series concludes with the suggestion of an amicable separation between Tim and Dani, Caulfield's apparent resignation, and the opportunity for Dani to return to her position at the school if she chooses.
