把恋爱也忘记 恋も忘れて

It is the story of a single mother who works as a bar hostess to provide for her son. Her goal is to make sure he gets a good education so that he can become "a big man." The trouble begins, as it often does in Japanese movies, when the son finds out what it is that his mother does--or more specifically, when his friends find out and start to ostracize him.
