The Little Boy Scout (1917)

Justina Howland lives in Mexico near the U.S. border with her uncle Miguel and his son, Luis Alvarez. The uncle plans to have Justina marry Luis in order to get the money which she will inherit. Matters come to a climax when Miguel sends for a priest and announces the marriage will take place at once. Justina escapes on the mule that brought the padre to marry her and crosses the border, where she is given shelter by the soldiers under command of Lieutenant Morton.
