The Drews relocate to the country in an effort to clear a family friend of a murder charge. Upon arrival Carson Drew meets the charming Edna Gregory, triggering an intense jealousy in Nancy as she fears losing her father to the woman’s advances. When the disinterested local sheriff refuses to consider the family friend’s innocence, it’s up to Nancy and reluctant boyfriend Ted Nickerson (whose family is vacationing at a nearby lake) to find the real murderer and clear “Uncle Matt’s” name.
