Expressway (2016)

A syndicate old-timer named Ben needs to do one last assignment before the boss he works for grants him his much delayed retirement. Assigned to be his partner is the neophyte Morris, a trigger-happy, sadist who yearns to impress the syndicate boss. For Ben, this last assignment turns out to be a journey of introspection, self-healing and redemption. With this awakening, he takes it upon himself to pull Morris out of the eventual hell-of-a-life he says he has lived as a hitman.
