A band of rosy-cheeked children go on a rampage in this British horror flick from director Tom Shankland. The film opens with Elaine (Eva Birthistle) bringing her husband, Jonah (Stephen Campbell Moore), and their three children to celebrate New Year's with her sister Chloe (Rachel Shelley). Chloe is married with two children of her own, and her family lives in a gorgeous cabin set deep in the woods. Soon the cozy home is filled with scampering kids and Casey (Hannah Tointon), Elaine's sullen teenager. As the families reunite and settle in, hidden tensions and secret flirtations pass back and forth between every one 16 and older, while the children shriek and play. When Elaine's son Paulie (William Howes) gets sick, she chalks it up to car sickness, but by the next day, he appears to be worse. Soon the other children begin to act strangely as well. When a fatal accident occurs, everything falls into chaos, and accusations fly among the adults. The real killers are soon revealed, and some truly gory (colored pencil through the eye, anyone') murder scenes quickly follow.

While some might find the film's premise never quite makes it out of camp territory, it cannot be argued that Shankland doesn't do a solid job of presenting some truly interesting, well-rounded characters. Despite the blatant violence of some scenes, much of the film is full of subtle, mood-setting shots. These quiet, unsettling images--branches cracking with ice, the blank stare of a child's doll--give the movie its real creep out factor. Size three pink Wellingtons have never looked so sinister.
