Christine of the Big Tops(1926)

When her circus-performer parents die in an accident, Christine (Pauline Garon) is raised by other circus-performers, including Hagan, a balloon-vender, and Pete Barman as her guardians. When she grows up, she asks to also become a performer, and Barman agrees. Bob Hastings (Cullen Landis) joins the traveling circus as its doctor, and he and Christine fall in love. This angers Barman, who is also in love with her.
