What I submitted to my screenwriting teacher as a second draft, and her comments.

Working Title - "Going Home Again"
Genre - Family Drama like "Field of Dreams" and "Frequency".
Proposed Length - 110 pages.

While at home for a baseball series, a 38 year old baseball player comes to term with his unspectacular career and his impending retirement. During the night of his birthday celebration and a family reunion, the journeyman baseball player confronts his strained relationship with his dying father, his trouble relationship with his wife and estranged 10 year old son, and the old sibling rivalry with his younger brother.

Final scene - funeral reception for father at parent's home. Scene with main character and son talking about grandfather, looking at the old clippings, tells him afterwards they'll play catch in the backyard just like how grandpa played with him.

Notes from Julie O:
to have the ending I have, main story is really about the main character's strained relationship with his 10 year old son - it's the A story, everything else, story with dying father, brother and wife, is a B story. Son represensts hope for the future, so that he doesn't end up like his father, and make the grandfather's death be in vain.

Julie O suggested I craft four plots or spines:
main character and son
main character and dying father
main character and brother
main character and wife.

Then weave all four plots together into one story.
