Set in the dead of night in New York City, the story centers on Marcus Kane, a disgraced former quantum physics researcher turned freelance data recovery specialist. Plagued by the wartime death of his younger brother Evan, Marcus suffers an unthinkable, recurring nightmare: every night at 23:53, his phone automatically receives a murder surveillance clip timestamped 23:58, where he himself is always the killer. No matter how hard he tries to intercept the victims shown in the premonition footage, he only ends up reenacting the fatal scene, making him the prime suspect in a string of homicides targeting former senior executives of tech giant Titan Chronos.
