In this third of RKO's "Mexican Spitfire" series, star Lupe Velez doesn't get any further west than Reno, Nevada. Lupe feels that her straightlaced husband (Donald Woods) is neglecting her, and thus seeks a divorce. Reliable old Uncle Matt (Leon Errol) shows up to straighten things out, which means that for the umpteenth time in this series he'll disguise himself as the veddy British Lord Epping. Before everything straightens itself out, Uncle Matt finds himself in dutch with his own wife. We all know that Lupe and her hubby will get together: otherwise there wouldn't be a fourth "Mexican Spitfire" picture.
