Shock

In San Francisco, Mrs. Janet Stewart checks in a hotel late night to meet her husband Lieutenant Paul Stewart. However Paul does not arrive and Janet goes to the balcony in the middle of the night after a nightmare. She witnesses the renowned psychiatrist Dr. Richard Cross asking for the divorce to his wife and having an argument with her. Out of the blue, Dr. Cross kills her with a candlestick and Janet has a nervous collapse and stays catatonic in shock in her room. When Paul arrives and sees his wife, he summons Dr. Stevens. After the examination, Dr. Stevens tells that Janet has had a psychological breakdown and recommends Dr. Cross to treat her. When Dr. Cross comes to the room, he realizes that Janet might have seen him and he tells that she needs to be interned in his clinic. He calls Nurse Elaine Jordan, who is his lover, and they take Janet to their clinic. He decides to make Janet forget the incident but then they decide to discredit her proclaiming Janet insane. But when the District Attorney O'Neill asks for the authorization to Dr. Cross to carry out an autopsy in his wife since he believes that she might have been murdered, Elaine tells that Dr. Cross must kill Janet.
