The poor mother of seven children, each named for a day of the week, goes off to market promising to return with individual gifts that each child has requested and admonishing them to lock the door to strangers and not to touch the fire. The gullible children are tricked into disobeying their mother by the witch, Heckedy Peg, who turns them all into various kinds of food. The mother can rescue her children only by guessing which child is the fish, the roast rib, the bread, etc., a trick she neatly performs by matching each kind of food with the gift that each child had requested
