Once there was a lighthouse keeper called Mr. Grinling. At night time he lived in a small white cottage perched high on the cliffs, and in the daytime he rowed out to his lighthouse to clean and polish the light. When Mr Grinling decides he needs a hobby, he tries everything from baking to birdwatching. But one morning, a stroll along the beach inspires Mr Grinling to take up something very different...and before too long Mr Grinling surprises everyone...
