Prosecution Witnesses

London's famous criminal defense lawyer Sir Waffey (Charles Laughton) ) received treatment for a heart disease, but his body was still weak. On his first day at home to recuperate, the nurse strictly supervised him in taking medication and stopped smoking and drinking. In order to make it easier for him to go upstairs, the housekeeper even built an elevator for him. However, all kinds of care and attention had no effect on this rebellious and sharp-tongued barrister. On the contrary, he was more excited by the complaint. Lawyer Mayhew and his client Wall (Tyrone Power) come to visit and ask him to come out to litigate the case. It turned out that Wall met the rich woman, and the two met happily. Although the servant was full of contempt for the egg beater he invented, the rich woman was full of love for him and even revised his will and left him 80,000 pounds. However, the rich woman was brutally murdered. As a result, Wall became the police's number one suspect. His only witness is his wife Christine (Marlene Dietrich). However, the latter's indifference and calmness when she came to the door made Sir Waffey suspect that there was something hidden in it. Behind the complicated and confusing cases, there are many interlocking and ulterior secrets hidden... This film is adapted from Agatha·
