The MacGrieff's, a wealthy Scottish family, are rocked by a grisly murder on their estate. The youngest, Corringa (Jane Birkin), finds herself embroiled in an increasingly bizarre saga. As the bodies pile up, Corringa starts suspecting someone within her own family of the murders, is it her arrogant cousin, James (Hiram Keller)? Their seductive French teacher, Suzanne (Doris Kunstmann)? Her own mother, Alicia (Dana Ghia)? Or can the legend of the MacGrieff family be true? That any MacGrieff killed by the hands of another will bring about a vengeful curse on the whole clan.
