Soldiers in a rural part of Lancashire (England) are being killed by an unidentified beast – the authorities suspect a leopard – that is only killing men in uniform.
Meanwhile, near the small rural town of Littlemead, elderly sisters Ellie (Beryl Reid) and Joyce (Flora Robson) Ballantyne, have kept their brother Stephen (Dafydd Havard) bricked up in their cellar for the past 30 odd years
Hearing that a soldier from the nearby army camp has been murdered, the sisters check on Stephen and discover he has dug a tunnel and escaped. Finding another dead soldier in their shed, Ellie and Joyce – not unreasonably – deduce that their brother is responsible.
