Chalk Marks_

Young Herbert Thompson, wanting to attain wealth and social status, marries Ann Morton, who comes from a rich and prominent family, throwing over pretty young Angelina Kilboure, who really loves him. Years later Herbert has become the local District Attorney and has two children, Bert and Virginia. One night Bert, a patron at a seedy roadhouse, defends his sister's honor from a ruffian and winds up killing the man. Angelina persuades Herbert to leave his post as D.A. to defend his son in his murder trial. Herbert wins the case, but it turns out to have unexpected consequences.
