It's possible you're thinking of a different movie, or perhaps "The Advocate" is a lesser-known film. To help me figure out what you're looking for, could you provide:
* The full title of the movie
* Any other details you remember about the film (e.g., the year it came out, the genre, the actor who played the main character)
* Any details about the daughter character (e.g., her name, her age, her relationship to the main character)
With more information, I can try to help you find the movie and the actress who played the daughter.
