Synopsis by Hal Erickson
Alan Holubar was both star and director of the Universal production Heart Strings. When little Johanna (Virginia Lee Corbin) is abandoned by her irresponsible mother, the child is adopted by lonely Dr. John McClean (Holubar). Growing into attractive womanhood, Johanna (now played by Francelia Billington) falls in love with young medical student Gerald (Paul Byron). Unfortunately, the boy falls under the spell of predatory older woman Leonie (Maud George) -- who, of course, is Johanna's long-lost mother. It falls upon Dr. McLean to clear up this mess and bring Johanna and Gerald together again.
