Die Abenteuer von Emily und John

Today Emily and John are out and about in the nature reserve with Chris. They want to watch lions. But they are not so easy to find! Chris is a lion specialist and knows how to track down the shy big cats! Some lions wear radio collars and send signals. Chris can receive these signals and so he knows roughly where the animals are. But the park is big and there aren't many lions left, will it work?
