Board a small ferry on a misty Scottish morning and island-hop through the Hebrides. Follow Callum, the weathered ferryman, as the boat makes its slow, unhurried way across grey water — pulling into quiet harbours, delivering crates, pausing while sheep are coaxed aboard, then heading out again into the mist. Let the steady hum of the engine, the rocking of the hull, and the soft grey light over green hills carry you gently to sleep.
