Twins Grace and Marty end up going to live with their Uncle Wolf, whom they've never met, after an accident leaves them without parents. This uncle is a veterinarian and is hunting cryptids-or mysterious creatures whose existence has never been proven. Grace and Marty are taken on quite an adventure when a mishap leaves them in the jungles of the Congo all by themselves. Not only are they alone but there are supposed to be cryptids in this jungle and there are others hunting these cryptids, who will do anything to get to them first.
