Nancy and her sausage dog Roger return for a summery - and mischievous! - day at the beach. Nancy is visiting her cousin Jack at the seaside, when his cheeky pet parrot flies away. 'After that parrot!' cries Nancy, and sets off in hot pursuit, racing across the bustling beach, the colourful funfair and even the foaming sea. But - uh-oh! There's lots of mischief to be had beside the sea - and Nancy is VERY mischievous!
