During a post-Civil War Wyoming winter, a stagecoach bearing a bounty hunter (Kurt Russell), his foul-mouthed prize (Jennifer Jason Leigh), an ex-Union officer (Samuel L. Jackson) and a lawman (Walton Goggins) makes it's way towards Red Rock. The worsening snows force them to shelter at a general store occupied by a caretaker (Demian Bichir), a cowboy (Michael Madsen), Red Rock's hangman (Tim Roth), and an aged Confederate general (Bruce Dern). As the blizzard traps them within-possibly with no escape-resentments, greed, and hidden agendas emerge that might destroy them before the elements do, in Quentin Tarantino's moody and stylish sagebrusher.

This superhero drama follows Central City forensic scientist Barry Allen (Grant Gustin), who is given the power to move at lightning-quick speeds after a freak accident at a particle accelerator facility. As a man who has always had a propensity for helping others and doing good deeds, Allen uses his newfound gifts to fight crime and evildoers.
