Synopsis by Hal Erickson
Though released after Hoppy Serves a Writ, the 1943 Hopalong Cassidy entry Border Patrol was filmed first, to capitalize on America's new "Good Neighbor Policy" with Mexico. Hoppy (William Boyd) and his pals California (Andy Clyde) and Johnny (Jay Kirby), investigate a group of crooks who've been smuggling alien laborers across the border. The villains treat their Mexican help as virtual slaves, killing off anyone who complains. When Hoppy and company invade the illegal work camp, they're subject to a kangaroo court and sentenced to be hanged. But with the help of the Mexican prisoners, our heroes not only escape, but bring the bad guys to justice. Border Patrol features Robert Mitchum in an unbilled bit, but it's difficult to determine whether or not this was his first movie appearance.
