In San Francisco a woman (Anabel Shaw) goes to a hotel where she'll meet her husband who has been a prisoner of war for two years. While wandering around in her room she notices from her balcony door, a woman having an argument and then suddenly being killed by her husband (Vincent Price). The next morning her husband walks into the room to find his wife in shock. So the hotel psychiatrist (Vincent Price) is called in to treat the woman and he soon realises he was seen and he sets out to destroy his only witness by drugs and hypnosis.
While on the set one day, Lynn Bari was talking with co-star Anabel Shaw and mentioned that she was a direct descendant, on her mother's side, of Revolutionary War hero Alexander Hamilton. Shaw revealed that she was a direct descendant of Aaron Burr, the man who killed Hamilton in the famous duel.
