Don "Red" Barry is Jerry. the adopted son of Tom Holden and returns with him and Holden's son Tommy to Coldwater, after an absence of fifteen years. Local residents recruit Holden to become sheriff and fight local gang led by Smoke Denton. However, the true leader is local banker.
Tom Holden is murdered after he discovers gold and is duped into signing mine deed as collateral for bank loan. Holden's son Tommy, replaces his father as sheriff. Meanwhile Don Barry as Jerry is framed and convicted for a murder. He escapes and begins quest for justice.
Those are just the highlights of this fast-paced story which seems to be the forerunner of contemporary television crime dramas, with multiple story lines.
The only version on DVD is poor quality with some scenes nearly black and with little contrast. The few 16mm prints floating around are fair at best unless someone knows better.
Don "Red" Barry doesn't rise above pedestrian or journeyman. Adequate is the most appropriate adjective. Moreover, he never wears a sombrero so I have no idea why he is the Sombrero Kid. Unfortunately, unless you want to watch 16mm, there isn't a good version on DVD.
