The devil's waltz

"Likeable but deadly outlaw Jack Posey is serving a long stretch of hard labor at Yuma Prison in Arizona when his older brother pays him a visit and his fortunes turn for the better. Dale a United States Marshal is there to offer Jack a deal approved by the governor. The outlaws in Jack's old gang--now led by his former number two man Tom Spooner--have become the most wanted in the West. Dale has been authorized by the governor to offer Jack a full pardon in exchange for helping to bring Spooner and the gang to justice. Jack accepts...not in the interests of justice but because he has an old score to settle with Spooner."--
