Strangers, The Story of a Mother and Daughter one of Ms. Davis' later triumphs. She plays a crusty New Englander whose estranged daughter comes home to try and mend fences. The tenuous relationship they develop is threatened when the daughter confesses that she's dieing of cancer. The subject matter could be maudlin and sentimental were it not for the well crafted script by Michael De Guzman in the hands of two such talented performers and the capable direction of Milton Katselas. This television production premiered on Mother's Day in 1979 and has since been largely forgotten. It's worth a revisit.
This production isn't available on DVD, but there was a VHS release of it in 1989 and you can still find copies on Amazon. It's also available on YouTube. The first installment, uploaded by BDEyes81 is above.
