A lovingly rhymed story about two different sisters and what it means to keep your word. For all fans of "The Lion Within You." High up in the mountains live the little red pandas Nima and Ketu, lovingly cared for by their mom. The sisters have promised to always stay close and look out for each other. But as they grow older, Ketu's curiosity grows stronger, until one day she sets off on a dangerous adventure. Now Nima faces a difficult decision: What should she do? After all, the two of them made a promise to their mom.
