Betty's blossoming romance with a dynamic young business executive turns to tragedy when a mysterious assailant forces her into a car accident that kills her friend.
Larry Reid, president of an aeronautics company, dies in the crash when Betty's car is forced off a
steep canyon road by the killer. She's trapped in the car, in a semi-conscious state, when she sees the murderer retrieve a letter from Larry's body.
However, Belly's story is rejected by many who believe that she actually caused the accident by driving while drunk. Barnaby, of course, believes her story and resorts to a hypnotherapist to probe Betty's subconscious in order to get at the truth. But something too terrible to remember blocks her recollection.
