When a young child forges a special connection with a seal on a trip to the seaside, their imagination takes them on an unforgettable journey. Through their eyes, we have a chance to explore everything the amazing beach and wide, wide sea has to offer - until suddenly a violent storm blows in. The next morning the beach is covered in litter. Whose fault is it? And who can fix it? Lyrical, beautiful and inspirational, this is a story of imagination, of joy in nature, and of the nascent realisation of a young child that plastic pollution is our fault, but that together we can be the solution.
