Don "Red" Barry plays Lt. "California Joe" Weldon in this Civil War-era western. Joe is a Union undercover agent, whose job it is to stem the activities of Southern sympathizers. It turns out that the rebels aren't villainous, merely misled. The picture's real heavy is a Quantrill type who intends to play one side against the other and then set up his own personal empire. Like most Don Barry vehicles of this era, California Joe benefits from the comic expertise of Wally Vernon. The simpering cuteness of juvenile actress Twinkle Watts, however, is a decided detriment. ~ Hal Erickson, Rovi
