A girl and her mischievous younger brother are enticed into a world of adventure and danger in this contemporary fantasy story. Lucy and Ricardo are sad and confused when their parents separate and they move with their mother into a creepy old mansion on the edge of town. There are strange powers at work in the old house, and the children find themselves traveling back and forth between their home and a war-torn foreign country where the children of the freedom fighters are being held captive. Together with two children who have escaped from captivity, Lucy and Ricardo help free the others and reunite them with their families. They learn to stop their sibling bickering and work together through their dangerous mission. A tiger, a monkey, and a snake with supernatural powers assist and encourage the children in their heroic efforts.
