在这部福尔摩斯：斑点带子案剧情/犯罪片中,落魄孤立的古老邸宅，暴戾潦倒的继父，庄园里晃荡的印度猎豹和狒狒......阴谋伴随黑夜降临，笼罩了孤立无援的孪生姐妹。
暴风雨之夜，寓意死亡的口哨声在阴森的邸宅飘荡，惊恐的狂叫声突然响起，婚礼在即的姐姐脸白如纸地倒在房门口，手指着继父的房间，在抽搐中死去。她弥留之际的遗言“那条带斑点的带子！”成为福尔摩斯断案的唯一线索。
As she fears for her life, Helen Stoner seeks Sherlock Holmes' assistance. She lives with her step-father Dr. Grimesby Roylott, a difficult man who is prone to bouts of temper. She tells Homes that some years previously, her older sister Julia had died in unexpected circumstances. She had asked Helen if she ever heard the sound of a whistle at night. Helen admitted that she had not. Just a few weeks before she was to marry, Julia came tumbling out of her room, screaming; she died within minutes. Now Helen, who is also soon to be married, finds that her step-father has moved her into her late sister's room. During her first night there, she hears the whistle that her sister had asked about.
斑点带子观后。穿越时光。
