The Los Angeles police put in their place when Miss Rachel and Miss Jennifer Murdock and their black cat, Samantha, very deae ex machina, help to prove the innocence of Jim Bayliss, earlier under suspicion for the death of his wife, now arrested for the murder of strange woman in his boarding house room. Miss Rachel and her unofficial sleuthing clear Bayliss in time for her traffic case to come up. Antidote for the tough school.
