The film essentially begins with the Three Mesquiteers traveling on a riverboat when they witness a card shark by the name of "Pierce Talbot" (George Douglas) being called out for cheating and getting into a fight over it. Things quickly escalate from that point when Pierce is thrown overboard after drawing a knife. Managing to reach the riverbank, Pierce eventually finds refuge in a house owned by fraudster by the name of "Hazelton" (Walter Wills) who has drawn up a phony deed to a tract of land encompassing over 13 million acres with the owner being a man that greatly resembles Pierce. As one might expect, it isn't long before Pierce assumes the name of this owner and, once the deed is accepted in court, he immediately lays claim to everything. Naturally, this causes a great deal of concern with the people who have already settled on this land and subsequently have to pay Pierce--now known as Luis de Serrano--an excessive price just to stay there. To that effect, a great number of these settlers are soon forced off of their ranches due to the exorbitant rent being charged--and that includes the Three Mesquiteers. That said, recognizing the inequity of the situation, the Three Mesquiteers don disguises and, under the alias of "Los Capaqueros" start robbing the rent collectors give the proceeds to those who need it the most. Needless to say, this angers Pierce to such an extent that he issues a bounty for their capture--dead or alive. Now, rather than reveal any more, I will just say that this was an entertaining addition to the Three Mesquiteers series due to the brisk action and the "Robin Hood" nature of the overall plot. Admittedly, there are a few issues that strain credibility--with the main one being the pure white horse owned by "Tucson Smith" (Ray Corrigan) being identical to the one ridden by a member of Los Capagueros. Yet nobody seemed capable of making that rather obvious connection. Only in Hollywood. In any case, although this clearly wasn't a great Western by any means, I thought it was one of the better films in the series, and I have rated it accordingly. Slightly above average.
