Wallace, perhaps the world's most absent-minded inventor, and his canine companion Gromit, have started running their own bakery, Top Bun, in their house at 62 West Wallaby Street, Wigan. <br /> <br />However, Gromit soon becomes worried when he reads reports in the local newspaper saying that several local bakers have disappeared during the year in strange circumstances, all caused by a dangerous Cereal Killer. Wallace is not worried, mainly due to the fact he is in love with bread enthusiast Piella Bakewell, former star of the "Bake-O-Lite" bread adverts. Gromit is therefore left running the business on his own, when he would rather get to better know Piella's poodle Fluffles. <br /> <br />While Wallace might be the 'toast of the town' at the moment, Gromit makes a shocking discovery and realises that his master is in danger, and so goes forth to solve the case before Wallace ends up brown bread.
