When wealthy spinster Emily French is found murdered, suspicion falls on Leonard Vole, the man to whom she hastily bequeathed her riches before she died. Leonard assures the investigators that his wife, Romaine Heilger, can provide them with an alibi. However, when questioned, Romaine informs the police that Vole returned home late that night covered in blood. During the trial, Ms. Frenchs housekeeper, Janet, gives damning evidence against Vole, and, as Romaines cross-examination begins, her motives come under scrutiny from the courtroom. One question remains, will justice prevail?
