It's very clear in this film: here's the idea, here's the people who believe in it, and here's what they do for it. Without unnecessary talk, doubt, reflection, endless monologues-dialogues and the like. The film is beautiful, the actors are young and cute, the atmosphere, the beautiful scenery, the music and the idea that is present in every scene and episode. If you want something, do it. You don’t like the way you live, the people you talk to are all bad, and the country and the government are mocking the people and doing what they want? So don't talk and talk endlessly about the same thing, just shut up and do something. Even if the smallest thing, which may not mean anything, but you do it, take the first step. And there, who knows, other people can follow you, do the same, and then it will go.
In this film, one guy got tired of sitting around talking to his friends about Scotland’s need for freedom and the English are all bad, and he decided to do something to remind people that they were Scots and free people. He came up with a plan, he was supported by a couple of three people, and with grief in half, they four carried out this plan. Completely trivial, at first glance, a thing, but the action took its effect. So here we go.
