To save her comatose mother, Kate Sutton, young Mabel scavenges for money and accidentally scratches Roger Howe's luxury car. She refuses his charity and insists on repaying him in the future, reminding him of his long-lost pregnant wife—until Mabel's pendant confirms that she is his daughter. As relatives scheme to force Kate into a bone marrow donation for money, Mabel risks her life to save her mother, but to no avail—until Roger shows up just in time.
