I'm looking for the name of the movie where a man becomes widow after his wife dies at birth, he raises his daughter. But actually his wife is not dead and she thinks her daughter is dead. I think the man was a boxer and they kidnap his daughter.

A scene that I remember is that the girl pays at the supermarket with too many change and the caissiere yells at her. Her actual mother stands in the row behind her and then yells at the caissiere for yelling at a child.
