It’s about a man recovering from mental health issues. We watch him as he opens the door of his sheltered housing bungalow, blinking in the sunlight. Next we see him attending a course at the local college. He waves cheekily at us through a classroom window, as if to say, ‘Look! I’m trying to get better – all those taxes you pay for my treatment are not wasted.’ But now he’s walking on a sort of sea of crushed forest, formed from dead trees over millions of years. The sea heaves and swirls. He could be swallowed at any moment. Yet his smile radiates confidence.
