When a stagecoach is robbed and a passenger murdered, the boss of the company asks his pal โHoppalongโ (William Boyd) and his friend โWindyโ (โGabbyโ Hayes) to travel, incognito, to get to the bottom of things. We know that โKellerโ (Robert Fiske) is the man behind the crimes and that he has stolen $30,000 from the now dead husband of โAnnโ (Charlotte Wynters) but he is not expecting this great milk-sop of a dandy to arrive replete with bow-tie, and so โHoppyโ is able to infiltrate the town and observe just how the stolen cash is being laundered through itโs casino. Needless to say, neither โAnnโ nor daughter โDorrieโ (Jan Clayton) are best pleased with this hapless man, but that is bound to change once he gets onto the scent of the perpetrators and brings them to book. Of course the result is that certain, yes, but this is still a solid adventure western with plenty of action, duplicity and Fiske makes for quite a decent baddie as things hot up to a well staged conclusion where luckily nobodyโs aim is much good. Boyd is competent here and Hayes serves well as his lively foil and for an hour itโs an amiable story of greed versus good.
