While working as a research technician for the wealthy Allan Pruitt, Kimble gets involved in the business of Allan's teenage daughter, Janice, who returns home after spending a year in a mental hospital recovering from a nervous breakdown after witnessing a young boy under her care get killed by two vicious stray dogs. But Allan's new wife, Dorina, does not take a liking to Janice and plots to drive her insane by hiring a neighbor to make his pet dogs bark in the nearby woods and convince Janice that the dogs are alive (they were captured and put to sleep by the local dog catcher.) But when Kimble claims that he has heard the dogs barking, Dorina asks the local sheriff to investigate Kimble to find any dirt on him.
