A Dangerous Game (1922)

Gretchen Ann (Gladys Walton) runs away from her foster parents and is sheltered first by train brakeman Bill Kelley (William Robert Daly), then by elderly oilman Pete Sebastian (Edward Jobson). After Gretchen Ann keeps Sebastian from being duped by a medium, he sends her to a fashionable school, asking that she agree to marry him when she returns. She accepts the condition, but Sebastian releases her from the commitment when he realizes that she loves John Kelley.
