Děj filmu nás zavádí na periférii nejmenované průmyslové čtvrti. Podivínský samotář Henry Spencer se právě dovídá, že jeho přítelkyně Mary je těhotná. Místo roztomilého novorozence ale na svět přichází jakési monstrum. Mary se s touto situací není schopna vyrovnat a Henryho i s potomkem opouští. Nekonečné halucinace dovedou Henryho nakonec až k zoufalému činu...
Artful Penny could indeed draw anything she wanted with her magic crayon and it would spring into life. A fantastically useful toy to have. Only her best friend friend Dennis knew her secret so the two had acres of fun winding up adults, nosey-parkers, bullies, bad guys, teachers and ne'er-do-wells with her creations, or solving problems for folk, or sketching their way out of tricky situations. Penny would scribble away, her arm becoming a blurr as she worked and then - hey presto! - her line drawing would leap off the drawing surface as a fully-formed 3D object.
