Portia on Trial (1937)

Lady lawyer Portia Merryman (Frieda Inescort) defends woebegone Elizabeth Manners (Heather Angel) who is on trial for shooting her lover Earle Condon (Neil Hamilton). Ironically, Portia herself had once had an affair with Earle's father, powerful publisher John Condon (Clarence Kolb). She has a pretty good idea of what is going on in Elizabeth's head, since she herself was on the verge of killing Condon when he ruthlessly took custody of her illegitimate son (not Earle, though that certainly would have brought things full circle). As Portia toils and strains to free her client, she carries on a romance with Dan Foster (Walter Abel) - the attorney for the prosecution. LA Law and The Practice have nothing on this one!
