On a languid midsummer's day in the countryside, old Adam Godley, a renowned theoretical mathematician lies dying. Gathered around him are his family: Adam, his son; Adam's wife; Petra, his daughter; his wife Ursula, stepmother to his children; and his daughter's young man. But the Godley family is not alone in their vigil. Around them hovers a family of mischievious immortals who begin to sir up trouble to sometimes wildly unintended effect.
