Pip lives on island and is the captain of his boat Puffin, which he sails to the mainland to collect the things that the islanders need.

One beautiful morning Pip and his crew set off as usual, but when they reach the mainland they learn that the weather is about to turn foggy. As they journey home the fog descends and they are in trouble: how will they avoid the dangerous whirlpool and get safely home? Maybe the crows can help.
