Old friends converge on a seaside country settlement. Last year they were teenagers, but now they don’t recognize each other. Boys have turned into men, girls into strangers you’re afraid to approach. But you really want to. And “The Old Mill” has a life of its own: the sea, dancing, love, gossip. No one realizes these are the last carefree days—tomorrow the settlement will be cut off from the world, and not everyone will survive.
