An elderly Margaret Thatcher talks to the imagined presence of her recently deceased husband as she struggles to come to terms with his death while scenes from her past life, from girlhood to British prime minister, intervene.

Margaret Thatcher: Watch your thoughts, for they become words. Watch your words, for they become actions. Watch your actions, for they become habits. Watch your habits, for they become your character. And watch your character, for it becomes your destiny. What we think, we become. My father always said that. And I think I am fine.
Margaret Thatcher: "How do you feel?" / "Oh, I don't feel comfortable." / "Oh, I'm so sorry, we the group, we're feeling..." Do you know, one of the greatest problems of our age is that we are governed by people who care more about feelings than they do about thoughts and ideas? Now, thoughts and ideas, that interests me.
Airey Neave: If you want to change this party, lead it. If you want to change the country, lead it.
Alexander Haig: So you are proposing to go to war over these islands. They're thousands of miles away, a handful of citizens, politically and economically insignificant, if you'll excuse me.
Margaret Thatcher: Just like Hawaii... I imagine.
Margaret Thatcher: It used to be about trying to do something. Now it's about trying to be someone.
Margaret Thatcher: Sink it!
Young Denis Thatcher: Margaret, will you marry me?
[a pause, Margaret stares at him]
Young Denis Thatcher: Well?
Young Margaret Thatcher: [Margaret is still staring, Denis kisses her hand] Yes. Yes!
Young Denis Thatcher: [Margaret starts to cry from happiness, Denis leans in for a kiss, but she suddenly pulls back] What?
Young Margaret Thatcher: I love you so much but, I will never be one of those women, Denis. Who stays silent and pretty on the arm of her husband. Or remote and alone in the kitchen - doing the washing up, for that matter.
Young Denis Thatcher: [interrupts] I'm going to help with that...
Young Margaret Thatcher: No. One's life must matter, Dennis. Beyond all the cooking and the cleaning and the children. One's life must mean more than that. I cannot die washing up a teacup! I mean it, Denis. Say you understand.
Young Denis Thatcher: That's why I want to marry you, my dear.
Margaret Thatcher: It's time to get up! It's time go to work! It's time to put the great back into Great Britain!
Margaret Thatcher: We will stand on principle... or we will not stand at all.
Denis Thatcher: You'll be fine on your own, love. You always have been.
Margaret Thatcher: This lot seems bound to do the same... but they will rue the day.
Margaret Thatcher: Where did you go?
Denis Thatcher: South Africa.
Margaret Thatcher: Ah, yes.
Denis Thatcher: How many days passed before you realized I'd gone? Probably had to ask the cleaning woman where I was.
Denis Thatcher: One likes to make an effort. A snifter?
Margaret Thatcher: You're dead, Denis.
Denis Thatcher: Ah well, if I'm dead, who are you talking to? Shall we dance?
Margaret Thatcher: Oh...
Margaret Thatcher: [switching off television] I don't recognize myself.
