In the neon-drenched underworld of Tokyo, a meticulous and ruthless assassin named Kate, played by Mary Elizabeth Winstead, finds her perfect record shattered when she is inexplicably poisoned. Given less than 24 hours to live, she is thrust into a relentless race against her own impending death. With her body failing and time evaporating, Kate transforms her final day into a violent crusade for answers and vengeance, targeting the shadowy figures who betrayed her. Guided by her enigmatic handler, Woody Harrelson, and forging an unlikely connection with the teenage daughter of a past target, she cuts a bloody swath through the city's criminal hierarchy. Directed by Cedric Nicolas-Troyan, this high-octane thriller is a pulse-pounding journey of redemption and retribution, blending brutal, stylized action with a poignant emotional core as a dying warrior seeks to settle her final score.
