Unforgiven (1992)

Outlaw and former murderer commits to one last job in Western from Clint Eastwood 

Delilah has her face is slashed by a cowboy, and, furious that the Sheriff merely orders they hand over some ponies to Delilah’s boss for the lost revenue, puts a bounty on the cowboy and his friend. A young man, the Kid, asks outlaw and notorious murderer Will for help in killing the cowboys, and Will, in need of cash, reluctantly accepts, returning to the bloody life he thought he’d left behind.
