Bob's sister, Ellen, has become engaged. Bob's neighbor, Howard, has fallen in love again. Taken separately, these two events in Bob's life would be reason for celebration. Unfortunately, Howard has fallen in love with Ellen, and is determined to woo her away from her fiancée. Martha Scott makes another appearance as Bob's mother. Written by Martin Cohan, "A Love Story" made its initial network appearance on February 9, 1974. ~ Hal Erickson, Rovi
