what a witty and brilliant british thriller . a mother be lose her son who die in a motorcycle accident . his heart be tranplanted into the body of a young man who have suffer from a heart attack . his wife be seek love and satisfaction with another guy . and the mother be fall in love with the husband who own the only remain sign of life of her beloved son and his heart . this all lead to a fatal menage a quatre with a deadly end for nearly everybody . this film be really heart grabbing and a perfect mixture of some hopeless love affair and a psycho thriller and lot of good acting ( especially by sakia reef who play the despaired mother and rhys ifans a arrogant tv manager ) and some really witty metaphor about the often use topic heart . love song and quote and heart beat and heart attack and etc . you have never see so many reference to the love symbol heart in a movie . at the end of the film and you see a shock scene of the bloodstained mother walk around with a human heart in a bag . the ( often heart relate ) sound track song be also very suitable and and after watch this movie you will never see all those heartache love story cliche the same way .
