The movie was about a woman with her young daughter (under 10), trying to escape from a mafia gang. The woman used to be the lover of the mafia member. There are few sex scenes. Then they broke up and the woman ran away. Her daughter was kidnapped or killed at home when the woman was away in the middle of the film. At the end of the movie, the woman loses all hope of life and sits on a bench. The mafia man sits in the back seat of a car driven by his butler, and uses a gun or rifle to shoot the woman in the head from a long distance through the car window. And then he closed the car window and committed suicide by shooting himself in the head.
The movie could be in English or Italian, and released between 2005-2010. Thank you!
