A young woman, kidnapped when she was a kid, returns home to the family she barely remembers and struggles to feel “at home.”

This sounds like a movie I would see - after I've seen commercials (and maybe a movie poster). Your logline needs to be a bit more fleshed out, and detailed.

A young woman who was kidnapped as a child comes home to a family she barely remembers.
