Three Desperate Men

When they learn that their brother Matt Denton (Ross Latimer) is awaiting trial in California, charged with train robbery, deputies Tom Denton (Preston Foster) and Fred Denton (Jim Davis) leave their home in Fort Grant, Texas and head west. They arrive in Tulare just in time to rescue Matt from being hanged, but a guard is killed during their escape. Ed Larkin (Rory Mallinson) who framed Matt, falsely accuses them of a long list of crimes. They return to Fort Grant so that Tom can see his sweetheart Laura Brook (Virginia Grey). They encounter outlaw Bill Devlin (William Haade) who persuades them to hold up a train which Laura unwittingly told them would carry a large payroll. Soon the whole territory is enraged at their deeds. They return to Fort Grant to hold up the two banks that are filled with huge sums of cattle money.

Three Desperate Men has a standard "good guys turn into outlaws by cruel circumstances" western plot which is given a lift by the presence of Preston Foster and Jim Davis, some lively shoot em up action and a fast pace. The finale features a real intense shootout- quite impressive. I think originally it was meant to feature the Dalton gang, but instead it was decided to have the desperate outlaws as fictional, which is a good idea. Notice that Denton isn't too far a stretch from Dalton.
