As the curtains lift on another installment of "The Ex-Wife," Jen (portrayed by Katie McGrath) strikes Jack (embodied by Tom Mison) across the face, her voice laced with warning as she declares it to be his final chance to desist. Jack persists, his plea for forgiveness hanging in the air, while Jen stands firm, demanding he leave her in peace. Jack vows to seek out Tasha and beseech her to witness his sincere remorse. Jen counters, insisting Tasha desires no such encounter. Jack argues fate, not his choice, orchestrated their daughter's demise. Jack then mentions Connor (played by Jack Fairbrother), commenting on his seeming kindness. Jen retaliates, questioning Jack's familiarity with the man. Jack counters, having witnessed their interactions and deemed Connor a decent soul, urging Jen to find happiness.
Post the introductory scene, Tasha (Celine Buckens) checks on Emily or Lucy (Liberty Miller), offering medication that might alleviate her discomfort. Meanwhile, the authorities secure Tasha's image from security footage. Escorting Lucy to a clinic, they discover she suffers from tonsillitis. As Tasha steps outside to retrieve her wallet, she spots police inspecting her vehicle. Calmly reassuring Lucy, Tasha suggests they'll devise a solution.
Returning home, Jen indulges in a passionate lip-lock with Connor. Tasha manages to locate a phone, attempting to reach Sam (Jordan Stephens). Her calls yield only voicemail, her pleas for help falling on deaf ears, even when she invents a tale of Emily's illness. Desperate, Tasha breaks into a client's abode, searching for medication for Lucy. Connor notices Jen's unusual demeanor, prompting her to confess her encounter with Jack and her desire for him to leave her be. Connor remains skeptical of Jack's intentions.
Elsewhere, Tasha reads to her daughter, while Jack reads to Hayley's children. A call from Johnny, who has tapped Jen's phone, draws Jack's attention. He inquisitively listens to their conversations. Tasha awakens to an eerie silence, realizing Lucy is missing. As she searches the house, the sound of a gun cocking echoes through the air. Maria (Anna Savva) confronts Tasha, demanding an explanation for her presence. Hayley interrupts Jack's reverie, reminding him of dinner plans. His hug prompts Hayley to request he ceases his odd behavior.
Tasha, in the throes of desperation, tries to explain her plight to Maria, who brands her a criminal. Emily's interruption, accompanied by vomiting, shifts Maria's focus. She instructs Tasha to clean Emily up in the bathroom and offers them temporary shelter. Maria insists on speaking with Tasha once Emily is settled. Later, Tasha implores Maria not to summon the police. Maria demands the truth if she intends to grant them refuge. Tasha fabricates a tale of her car being stolen and her distant home, pleading for a place to rest. Maria relents, granting them a single night.
As dawn breaks, Tasha awakens beside her daughter, engaging in a heartfelt conversation with Maria about their impending departure.
As Maria inquired about her identity, Tasha deceitfully responded with the name Serena. Soon after, the police arrived, announcing their search for Natasha Warrington. Tasha, eavesdropping on Maria's conversation with the officers, attempted to conceal herself while Maria spoke with one of them at the doorway. Once Maria successfully dismissed the police, she insisted on uncovering Tasha's true identity.
In the café, a patron named Andreas Koutsoftas inadvertently overheard Sam's voicemail. He revealed that Larnaca, mentioned in the message, was his hometown, situated in Cyprus. Sam, eager to Send him away, presented him with a gift and promptly shut down the café, making a swift exit. Meanwhile, Connor proposed to Jen that they celebrate by opening a bottle of wine. Jen stepped outside to retrieve her phone and unexpectedly encountered Sam, who revealed Tasha's whereabouts and her perilous situation. Sam asked Jen for a loan to give to Tasha, driven by his concern for her and Emily. Jen, however, firmly refused.
Tasha initiated a conversation with Maria about herself, pleading for them to just leave. Maria reassured her that she hadn't betrayed her, believing no child should be separated from their mother. She emphasized that Tasha was safe there and inquired if she was fleeing from Lucy's father. Tasha conceded that the situation was more intricate than that and confidential. She was acutely aware that her daughter would eventually confront her about the lies. Maria persuaded her to stay a little longer.
Jen received a message from Hayley, who soon burst in, distressed over finding sinister notes authored by Jack, who had gone missing. Hayley expressed her fear that he might do something drastic and inquired about River Point. Connor interrupted, but Jen felt compelled to accompany Hayley, unable to let Jack act out his impulsions.
Tasha shared her photographs and belongings with Maria, who admitted it was a vacation home. Maria, retired from the Cyprus National Guard where she served as an army guard, revealed her proficiency in combat and navigating divorce proceedings. She inquired about Tasha's reasons for being in Cyprus and suggested a safe way to communicate with her ex to reclaim what she deserved. Maria urged Tasha to confront her fears and cease running, asserting that feeling secure and at peace would be worth the battle.
Jen caught up with Jack, striving to prevent him from committing suicide. She revealed she had read his letter before anticipating his location. Jack reminisced about naming their baby and lamented his nothingness, fearing he had lost his voice. He empathized with Tasha's pain, acknowledging his blindsiding of her and her undeserved plight. Jack saw no purpose in apologizing if he couldn't confront her. Jen grasped him and disclosed Tasha's whereabouts. Jack's demeanor shifted, and he departed. Jen realized she had made a grave mistake.
Tasha checked her emails and discovered one from Jen, warning her that Jack knew her location. Connor sought clarification upon Jen's return, and she confessed that Jack had manipulated her. Connor inquired about Jack's leverage over her, prompting Jen to disclose the truth about Jack's daughter, who survived a crash from which Tasha had rescued her while unconscious. Connor questioned the relevance to Jen, who explained that Jack had deceived her, leading her to reveal Tasha's whereabouts. Jen raced against time to reach Tasha before Jack could harm her.
She has no desire to find herself behind bars or to bear the guilt of Tasha's blood on her hands. Connor implores Jen with all his might, begging her not to take this path. He is convinced that Jack will always emerge victorious simply because Jen allows it. Hayley discovers Jack in the midst of packing his belongings, an air of determination surrounding him. Jack asserts that he will do precisely what needs to be done, ordering Hayley, for once in her life, to keep her mouth shut.
As the night envelops the house, Tasha scours through it, her eyes darting from corner to corner, until she unearths a handgun. Maria catches her in the act, the weapon gleaming in the dim light. Tasha protests vehemently, insisting that she has no intention of stealing it. She lays bare her fears, explaining that Jack is coming for her and that flight is no longer an option. Desperate, Tasha begs Maria to teach her how to use the gun, so she may stand her ground. Meanwhile, Jack has arrived in Cyprus, his presence looming large over their intertwined fates.
