小男孩哈尼在森林中漫步时,发现了他的父亲——哈利的尸体。不同于一般谋杀案,这次因为多人都自认为凶手而令案情更加扑朔迷离。亚伯特船长(埃德蒙•格温 Edmund Gwenn 饰)认为是他在打猎射击时误杀了哈利;村落里的老处女葛雷布礼小姐(麦尔翠德•耐维克 Mildred Natwick 饰)认为是因为她为了保住自己的名声而用一只鞋子打了哈利的头部而造成他的死亡;与哈利感情不睦的妻子珍妮佛(雪莉•麦克雷恩 Shirley MacLaine 饰)则认为是她因为反抗哈利的性爱用装牛奶的罐子敲向他的脑袋而造成了他的死亡。真相最后能否水落石出?。Bipedalism, or 'two-footed walking', is the story of a painter who grew up in an orphanage and only years later learns the circumstances of his father's disappearance and death. Childhood memories bring the main character back to the past: he buys a house in the suburbs that used to belong to his family. In the basement, he finds his father's archives and scientific research documents on the hybridization of human race with related biological species. Studying the archive material, he unexpectedly finds evidence of efforts to renew the experiments on the remaining hybrid population. The painter then becomes a researcher, and consequently a victim. The basic idea of his father's research was to change, control and influence the process of human evolution - initially connected with eugenics theories of the period before World War II, and now being placed in a context of modern 'biotechnological' expectations by his former colleagues. The main character tries to recreate and realize his father's heritage, who was forced to cooperate with state terror organizations, using the results of his secret research. In a tragic manner, this information turns into the main character's reality, at first forcing him to reappraise his father's values and later driving him to madness.
