Dying of cancer, a woman tries to hide her condition and failing health from her daughter and friends while she struggles to live long enough to see her first grandchild.

Thanks Guys. Very encouraging and good suggestions. And yes, the lead's name is Grace. You can guess what the baby will be christened.

I really like the concept and I think that DPG logline is perfect.
I can see the tearjerker. All the emotions are there: anger, pain, shame, resentment, guilt, embarrassment and then love, pride, happiness and contentment.
With the title Graceful, assuming that the lead character's name is Grace, the tag line "Grace Full of Life" could accompany that movie.
Good luck with the script now!

I like the core of the concept and think it has commercial possibilities. There is a burgeoning demographic of aging boomers who can identify with the woman's predicament and struggle.

A suggested variation:

Dying of cancer, divorced by her husband for a younger woman and left destitute, a woman struggles to live long enough to see the birth of her first grandchild.
