The previous year, in the Sarek National Park, Laponia, a wildlife photographer takes a strange picture from his small airplane, of a bear running over the marshes. On its back sits a creature. It looks like a small monkey, but the photographer claims he has taken his first picture of a troll. Twenty-five years later, and back in Laponia, Susso runs a web page dedicated to searching for creatures whose existence have not yet been proven: the Yeti, the Loch Ness Monster, Big Foot. But Susso's true obsession is Trolls. When an old woman claims that a small furry animal has been standing outside her house, observing her and her five year old grandson for hours, Susso picks up her camera and leaves for what will become a terrifying adventure into the unknown. Because what if there really are trolls out there, and they're taking our children?
