"The Plunderers" is a color western from Republic Studios. While it's filmed in Cinecolor (which usually looks awful over time), the color on this YouTube copy is exceptionally nice.
John Drum (Rod Cameron) is a soldier in the US Cavalry and who is on a special undercover assignment. He is to convince everyone he's a horrible criminal in order to, hopefully, ingratiate him to a criminal gang...thus joining them and learning who is in the gang and what local is helping them. Unfortunately, over time, John becomes good friends with the gang leader and his heart isn't into bringing him to justice...where he'll hang. How to get out of this dilemma? An Indian attack out of nowhere!
The first 75% of the film is pretty good and there is an interesting possibly gay subtext as well. But the ending seemed like a giant cliche...as if the writer just thought an Indian attack was the way to resolve everything. An okay western overall...watchable, of course, but it could have been better.
