Julian, Dick, Anne and George had planned to visit Kirrin Island for their school holidays, but George's father, Uncle Quentin, is using the island to conduct some secretive scientific experiments. Uncle Quentin is later kidnapped by villains wanting his secret formula for alternative energy. Uncle Quentin is held in a sub-sea tunnel, and it is up to the Five to rescue him. During the adventure, the children befriend an artistic boy named Martin, whose guardian, Mr Curton, is part of the gang trying to steal the secret formula.
