'Missio' is based on two real events: the mysterious disappearance of Hull trawler 'The Gaul' in January 1974, and the disappearance of two cats in 2009. In both cases spirit communicators were used to discover what had happened to them. In the case of the cats, an animal communicator, working some 10,000 miles away, pinpointed exactly where the cats were to be located.

In this magical comedy, these two stories are combined to tell how a small boy, whose father disappears with The Gaul, meets a children's magician and the ghost of a 'hanging' judge, both of whom combine to change radically the boys outlook on life.
