Ever since her eighteen-year-old son, Erik, mysteriously vanished on a boat over thirty years ago keeping busy has helped her cope. One night she meets Marcellus, a giant Pacific octopus living at the aquarium who sees everything, but wouldn't dream of lifting one of his eight arms for his human captors - until he forms a remarkable friendship with Tova.
