Witness for the Prosecution

Leonard Vole finds himself embroiled in a murder accusation shortly after World War II. The wealthy widow Emily French is found dead, and Leonard is implicated due to his recent inheritance from her will.

Fresh from recovery in the hospital, Sir Wilfred Robarts decides to take on Leonard's case despite his doctor's strict orders. He is motivated by doubt over the accused's innocence expressed by his replacement barrister.

Sir Wilfred meets Christine Vole, Leonard's wife, and becomes suspicious of her demeanor. After a careful evaluation, he decides against calling her as a witness, fearing she could detract from the defense.

In a surprising turn, Christine takes the stand for the prosecution, offering compelling circumstantial evidence against Leonard. Her testimony fails to provide him an alibi and puts him deeper in legal jeopardy.

As hope dwindles for Leonard, a late-night phone call reveals shocking evidence against Christine. It is discovered that she had written letters to a lover named Max, indicating her intent to undermine her husband's defense.

The revelation of Christine's letters swings the jury's perspective, leading to Leonard's unexpected acquittal. However, Sir Wilfred is left with lingering suspicions about the sudden emergence of this evidence.

During the climactic courtroom scene, Christine confesses to having sabotaged her own credibility to exonerate Leonard. This shocking revelation adds another layer to the already complicated case.

In the heat of the moment, Leonard reveals his plans to leave Christine for a younger woman, showcasing his true character. This betrayal adds tension to an already electric atmosphere.

In a dramatic turn of events, Christine seizes a knife, an item submitted as evidence, and stabs Leonard in front of the shocked courtroom. This act seals her fate and turns the narrative upside down.

Following the tragic stabbing, Miss Plimsoll, Sir Wilfred's nurse, immediately cancels his planned trip to Bermuda. She pledges to assist in defending Christine Vole against the new murder charge, setting the stage for another intense legal battle.
