In Quest of Another's Suicide

Imagine a man aged 44 successful but alienated from self and family preparing to end his life by jumping in front of a New York City subway train. As he prepares to jump after much rehearsal we are given a full view of his internal meanderings. Ready to jump he admires a pretty woman on the opposite platform. He hears a train -- it is hers -- she preempts him jumping and is annihilated. He flees the subway becoming obsessed with whom this woman is who has redeemed him through her suicide. An odyssey follows -- he steals her diaries is implicated in her murder and finds love -- finally being released from his suicide.
