Director Sidney Salkow, about whose work I know very little, apparently cranked out quite a few B Westerns in his day, and this one is not exactly bad to look at, cinematographically, but it suffers from a poor script. On the plus side, it posts a gripping beginning but loses steam.
According to other reviewers, one desperado by the name of Jack McCall did exist in the real West, and apparently he was a bad seed, shooting people in the back, among other dastardly deeds!
Well, thank God for little mercies, Montgomery portrays an upstanding character who has inadvertently given away the position of his Union troop HQ to Confederate men in Union uniform, and he has to clear his name, and save his neck from the noose for high treason, by tracking down the man to whom he drew the map... on the back of an envelope addressed to Jack McCall. That tells you that Jack would never rate the sharpest knife in the drawer. Still, although he shoots other men facing them, he is not above jumping jail and enlisting the help of pretty Angela Stevens, known in saloon circles as thieving Rose.
That the reb who can clear his name survives years of secession war, postwar yank-reb enmity, and all the shootouts at Deadwood and all over the Far West, gives you a measure of this desperado's faith in favorable fate. More faith than I have in ever retrieving the 76' I invested in this BS fest. 5/10.
