(2008) The Children

Two families gather at an upscale English estate in late December. Elaine (Eva Birthistle) and her sister, Chloe (Rachel Shelley), along with their husbands and children, are set for a weekend of family bonding and winter fun. But when they arrive, one of the children becomes sick, and soon all the children exhibit strange behavior. The adults don't realize the disturbing truth until it is too late: The children have contracted a disease that has turned them into brutal, psychotic killers.
