《小先知》讲述的是： A comic tale of eccentric Michael Sleep (Pearce Quigley) who, since his darling Clea disappeared seven years ago, has lived a very ordinary life. He eats Shreddies, works in a DIY store, visits dad Brian (Michael Palin) and hopes for Clea to return. That is just the way it is, until one day dad Brian shares an old recipe involving rainwater, horse manure and more than a little alchemy. With recipe in hand, Michael sets out (albeit with some scepticism) to create Homunculi – magical prophesying spirits that can predict the future – in the hope they have the answer to his burning question, ‘will I ever see Clea again?’. Michael gets help from young workmate Kacey (Lauren Patel),an unlikely friendship that blossoms partly (but not wholly) through their mutual dislike of store manager Gordon (Crook). Their friendship adds to the frustration and intrigue of his nosy neighbours (Sophie Willan, Jon Pointing) who are obsessed with trying to find out what the hell is going on in the garden shed.
