直到有你是一部好看的喜剧爱情喜剧片 影视作品，Gwen grows up with her romantic mother constantly telling her the story of her courtship and marriage to her father. Nick grows up with an alcoholic father who can't hold a job and whose family, as a result, is forced to move all the time. The two are shaped by this - Gwen a romantic and Nick withdrawn, unsure of himself - as they watch the hugely popular sixties sitcom, One Big Happy Family. Years later, it is the star of that show, now a child actor gone bad with a history of detox and people always saying, I thought she was dead, Francesca Lanfield, who connects the two of them, after years of near-misses and almost encounters. Gwen is hired to ghost-write Francesca's autobiography, while Nick, becoming her lover, is the architect who is to design a building on Francesca's property. When Gwen decides to crusade to save Francesca's building, she writes letters to the newspaper which catches Nick's attention - and wins his heart.
