On a stormy night in New York City, a mysterious egg falls from the sky and smashes through the window of a rundown apartment building. From it a strange little spider emerges and is discovered by Charlotte, a rebellious, lonely twelve-year-old girl who's completely obsessed with comic books. She names it Sting. As Charlotte's fascination with the spider increases, so does Sting's insatiable appetite. Growing at a monstrous rate, neighbours and their pets start to go missing. Soon, Charlotte's family realise that they have all become the prey of a ravenous supersized arachnid with a taste for human flesh... and young Charlotte is the only one who knows how to stop it. Arachnophobes beware, your biggest fear just got bigger!
