A village in Nineteenth Century Europe is at first relieved when a circus breaks through the quarantine to take the local's minds off the plague. But their troubles are only beginning as children begin to disappear and the legacy of a long-ago massacre is brought to light. 此片不同于以往的 Hammer 吸血鬼的故事模式,描写由吸血鬼化身而成的巡迴马戏团来到一个已经遭受诅咒与疫情的村落,并且带来灾难的故事。此部片的故事背景设定在19世纪的塞尔维亚,这些如吉普赛人般的马戏团成员事实上都是会变身的吸血鬼。
