Victor Gilmore, a composer, is in love with his father Cyrus' secretary Dorothy Eldridge, but Dorothy marries his brother Robert, even though a doctor has told them that Robert can never father children. Dorothy, however, has never lost her hope to have children, and doesn't know that Robert is secretly supporting his former lover Flo Merrivale. The brothers' father eventually dies but leaves his estate to Robert, saying that he didn't believe that Victor was his son. This causes a huge rift between the brothers and a fight ensues, resulting in Victor's being thrown out of the house and family. Complications ensue.
