Los jinetes de la bruja (En el viejo Guanajuato)

An aging rancher is framed for the murder of a puppeteer; the family goes to a witch for help, who cajoles three wastrel caballeros to expose the plot, while dark forces - e.g., ghost puppets, a mysterious black-clad rider in a death mask - handle the more spiritual aspects of the puppeteer's revenge....

Oh, I forgot to mention the comedy as one of the caballeros gets chased around by his girl-friend for being a lazy ne'er-do-well, despite the fact that he gladly sings her folk-based pop-songs about love, etc.

Truly off-center bit of entertainment form Mexico, very well made, with crisp performances from all involved.

Warning: no subtitles on existing DVD release, the dialog is all in the elevated theatrical Mexican of its era.
