Miriam’s world turns upside down when she finds her husband Jack’s wedding ring hidden in a sock. Curious, she checks again the next day — and it’s missing. Jack is leaving the house every morning claiming he’s going to work, but when she calls his office, they say he hasn’t been in for days.
Suspicious, Miriam follows Jack and is devastated to discover he’s having an affair with a much younger woman named Tessa. Heartbroken but desperate to save her marriage, Miriam offers Tessa $100,000 — her secret inheritance — to walk away from Jack and never return.
Tessa accepts the money and promises to leave. But just days later, Miriam finds the wedding ring hidden again and rushes back to Tessa’s home — only to find Jack living there with her.
Tessa confesses she couldn’t stay away. Jack admits he no longer loves Miriam and wants a divorce. Furious and betrayed, Miriam demands her money back, but Tessa has already spent it on her young daughter Lily’s cancer treatment.
Devastated and driven by revenge, Miriam secretly poisons Tessa’s gym water bottle. But when Jack picks up their son Harry, he unknowingly gives him a sip from the poisoned bottle. Moments later, Harry collapses.
Jack calls in a panic, rushing Harry to the hospital. Miriam is left shattered on the floor, realizing the horrifying consequence of her own actions.
