Culling slate from coal all day long with a score of broken-down hags, young women, and girls, she lived a life of horror at home, beaten constantly by her father.

The mine receives a new over-man, Fergus Derrick (Ellis), trying to get on friendly terms with the drudging slaves, but meets a spirit of independence that proved the people better than animals.

On November 21, 1921, the Motion Picture News revealed that the playwright Elliott Clawson was working on rewriting the script of the Bluebird Photoplays feature Secret Love (1916), which was also based on the novel That Lass o' Lowrie's, thus revealing to the audience a bit of what they might expect but the release was rather received with surprise since the storyline was actually adapted directly from the novel but in a completely different way than how Secret Love was written with the highlights being major changes in the overall setting and a major change in genre.
