SPOILERS ---- Not in the course of the movie, but before its events, a little girl has been living with her (loving, but) criminal father, who has even more criminal associates, along with the dangerous animals he sells - snakes, tiger etc. - and she's left alone when he goes to jail (her alone in the police station is the first we see of her). A female police officer adopts her. When the father gets back out, the mother wants a restraining order against him because she considers him a danger to their mutual daughter (which he has been, of course, though only through those living conditions). At one point, the mother thinks that the father kidnapped her, and behaves accordingly, but we know it's not true. At the end, everybody knows that he loves his daughter, that he'll no longer be doing crime, and that they'll be seeing each other often enough, so it ends pretty well.
A mother thinks her daughter has been kidnapped, but we know it's not true. At one point, it seems like she IS being kidnapped after all, but she isn't.
