Highway to Heaven closes out its first season with episode one of a two-part story. Angel-in-training Jonathan Smith (Michael Landon) is assigned to a horse-breeding farm, owned by fabulously wealthy Mr. Armstrong (Stephen Elliott). The good news is that Armstrong's playboy son Garth (John Hammond) has fallen in love. The bad news, at least so far as Mr. Armstrong is concerned, is that Garth's sweetheart is Lizzy MacGill (Helen Hunt), the daughter of the farm's "lowly" horse breeder. Two regulars from Michael Landon's previous series Little House on the Prairie, Richard Bull and Noble Willingham, appear in supporting roles.
