Sarah Huttinger's return home with her fiance convinces her that the sedate, proper, country-club lifestyle of her family isn't for her – and that maybe the Huttinger family isn't even hers – as she uncovers secrets that suggest the Huttingers are neither sedate nor proper.
Unfortunately the movie Rumor Has It... is not yet available on HBO Max.
