Frisco Jenny

Frisco Jenny was orphaned by the 1906 earthquake and fire and has become the madame of a prosperous bawdy house. She puts her son up for adoption and he rises to prominence as district attorney dedicated to closing down such houses. When her underling Dutton proposes telling the DA that Frisco Jenny is his birth mother, she kills the underling not to cause trouble for her son now the successful DA, she must face execution. - IMDb
