Synopsis by Hal Erickson
The fraternal directing team of Chester and Sidney Franklin called the shots on the Fine Arts five-reeler Let Katy Do It. The story takes place in a tiny Maine village, where mousy Katy Standish (Jane Grey) works as general help on a family farm. Katy's sweetheart is dour Oliver Putnam (Tully Marshall), who proudly bears the title of the homeliest man in the county. Oliver later heads to Mexico to seek his fortune, while Katy stays behind to care for the seven children of her recently deceased sister and brother-in-law. Later on, Katy and the kids are invited to visit her Uncle Dan's (Ralph Lewis) home -- which, for the convenience of the plot, is also in Mexico. Katy and her seven charges manage to save Uncle Dan from a band of Mexican bandidos, leading to a happy ending for the heroine and her old flame Oliver. The script for Let Katy Do It was attributed to one "Granville Warwick" -- actually a pseudonym for the film's producer, D.W. Griffith.
