Eric Linden and Cecilia Parker, the stars of Grand National's first release In His Steps (1936), were reunited in the same studio's Girl Loves Boy. Linden plays Bob Conrad, the playboy son of town squire Charles Conrad. Much against his dad's wishes, Bob falls in love with Dorothy (Parker), the daughter of penniless widow Mrs. McCarthy (Dorothy Peterson). At the insistence of Conrad Sr., Bob weds Sally Lacy (Bernadene Hayes), but Dorothy's broken heart is mended when it turns out that Sally's divorce from her previous husband was never finalized. Like the previous In His Steps, Girl Loves Boy was scripted by cinematographer-director Karl Brown.
