Sarah Miller had it all: a successful tech career she traded for family, investing millions into her husband Ethan's architectural empire. Their seven-year-old twins, Leo and Luna, were her world, buzzing with excitement for their promised Fourth of July trip to Universal Studios. But Ethan had other plans – a yacht trip with his "pregnant" personal assistant, Tiff. Then, a chilling note: he'd taken the kids to the desolate Nevada wilderness for "character-building," leaving them with minimal water, one tent. Panic turned to horror when Sarah found them. Days later, search and rescue called: Leo and Luna, gone, victims of heatstroke and dehydration. While Sarah identified their ravaged bodies, Ethan threw a lavish pre-baby shower with Tiff, dismissing Sarah's call about their dead children as a "dramatic stunt." He returned only to smash their photos, allow Tiff to spill their ashes, and brutalize Sarah for trying to mourn. How could a father abandon his children to such a horrific fate? How could he deny their deaths, celebrate with his lover, and then violently silence their grieving mother? The cold, calculated cruelty was unfathomable. But a desperate, heartbreaking voicemail from Leo's last moments and a shocking truth about Tiff would shatter Ethan's narcissistic world, setting off a chain of events that would force him to confront the monstrous consequences of his actions, and leave Sarah to pick up the pieces of a life utterly destroyed.
