Marooned on an island following a picnic, nurse Barbara Deming is victimized by Doctor Clayton, head of the hospital in which she works. After they are rescued, Clayton embarks on an arctic expedition led by Neil McClintock. Barbara gives birth to a daughter, who is secretly cared for by a fellow nurse. She later marries Neil without telling him about her daughter. Clayton visits the McClintock home, where he informs Neil of Barbara's secret. Meanwhile, her child becomes dangerously ill and Clayton saves her life. The doctor leaves for another arctic voyage, and Barbara's daughter becomes a part of the McClintock family.—AFI
