"On Broadway" tells the story of Jack O'Toole, a 30-something Boston everyman, who writes a play about his dead uncle as a way to reconnect with his hard-nosed dad. With no money and just his gut to guide him, Jack quits his job as a carpenter so that he can mount a production of his play on the only stage he can afford: in the back room of his neighborhood pub, on a little street called Broadway.
