In the conclusion of a two-part story, wealthy horse breeder Mr. Armstrong (Stephen Elliott) is still dead set against the romance between his playboy son Garth (John Hammond) and the daughter of Armstrong's head trainer MacGill (Noble Willingham). It is up to angel-in-training Jonathan Smith (Michael Landon) to smooth out the course (or in this case, the bridal path) of true love. Complications ensue when the young couple elopes -- with Garth unaware that his sweetheart is suffering from cancer. A decidedly pre-Mad About You Helen Hunt guest stars as feisty Lizzy MacGill in this, the final episode of Highway to Heaven's first season. ~ Rovi
