In a disputed border town, the US Army waits for word from Washington as to the rightful country it belongs, while dealing with a rowdy pack of Mexican soldier/bandits. Into the mix rides seemingly mysterious stranger Anthony Steffan, who looks like a dandy but has a few deadly tricks up his sleeve.
Unfortunately the movie Gentleman Killer is not yet available on HBO Max.
