這是美國歷史上一個真實的故事，也是懸而不決最久的一個懸案。1957年12月，一個暴雪的夜晚，一個七歲的小女孩在伊利諾斯州西克莫的街頭失蹤，隨之而來的是各種可怕的真相，謀殺、家族祕密、臨終的懺悔，而兇手的親生姐姐固執地下決心一定要為小瑪麗討回公道。
Footsteps In The Snow is the true story of the coldest cold case ever solved in American history. On a blistery night in December 1957, a seven-year-old girl disappears off the streets of Sycamore, Illinois, and what follows is a gripping tale of murder, family secrets, deathbed confessions and the dogged determination of the killer's own sister to find justice for Little Maria.
