Quebec, 1888. A snowstorm traps five people in a remote saloon. One is Dòmhnall Morrison, the Megantic Outlaw, one of the most notorious villains of his day – to all but his own community. Another is a badass Barra woman, Màiri MacNeil – a whiskey-fueled, pistol-slinging, bounty hunter. She has history and a score to settle.
