Christine of the Big Tops (1926)

When her circus-performer parents die in an accident, Christine, a young girl, 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 joins the traveling circus as its doctor, and he and Christine fall in love. This angers Barman, who is also in love with her.
