Harriet's mother and her nanny tell Harriet not to play with the box of matches while alone at home. Harriet doesn't listen, grabs the box, lights a match and plays with it. She doesn't put it out in time and her dress catches fire and Harriet burns until all that is left are her ashes. All the while her two cats try to warn her that she might die if she plays with fire. In the end, they can do nothing but cry over her ashes.

Don't play with fire!
