在这部我的姐姐，我的爱剧情/历史/爱情片中,《我的妹妹我的爱》中，兄妹之间的乱伦是以18世纪古斯塔夫三世统治时期为背景的，但是看来又好像是受到伊丽莎白时代的剧作家John Ford及其作品《真遗憾她是个娼妓》的启发。
Sweden in 1782. A young nobleman, named Jacob (Per Oscarsson) returns from France to his home and cherished sister Charlotte (Bibi Andersson) who is engaged to Baron Alsameden (Jarl Kulle). The siblings close relationship becomes incestuous and with fear that the disclosure of Charlotte's pregnancy will make society view them as libertines, the lovers ultimately choose to part, Jacob decides to leave the country and Charlotte if left to marry the Baron.
