London joins a lady reporter, June Wilson, and her photographer-assistant,
Lombardi, who are reporting on the disappearance of a macaw from a zoo.
London suspects an elderly custodian, Fred Spooner, who is in forced
retirement with an expressed love for the animals once in his care, of being
involved in the macaw's disappearance.
After the vanishing of a cougar kitten from the zoo, Wilson and Lombardi investigate and are told by the curator, Dr. Devereaux, that several other animals have gone missing in past
London leaps into Spooner's vehicle as Spooner is driving to his farm home. He finds the missing cougar kitten in a cage in the back seat. Spooner admits to London that he is taking the animals because they have been the only family he has ever had and that he cannot be parted from them by his retirement from the zoo.
London follows as Spooner pursues the cougar kitten that runs away from Spooner's farm where all the missing animals are, and watches as Spooner attempts to reach the cougar in a tree by climbing a wooden ladder, a step on which collapses and causes Spooner to fall to break a leg.
London runs to find Wilson and Lombardi and guides them to Spooner's
farm, where they find all the missing animals and the incapacitated Spooner,
who admits to taking the animals to keep them near to him.
Spooner is forgiven and allowed to visit the zoo whenever he likes to see his animal "family".
