Belinda Krüger was pretty sure that working as a governess in an American family would be a perfect opportunity to improve her English and earn some money in the same time. Mr. and Mrs. Lewis were very nice people, but their daughter Rebecca was not happy about to have a governess. She was pretty sure that she's too old for that. So she started to look for any opportunity to make the German's life harder right from the day Belinda arrived.

On the third day Belinda and Becky were playing tennis, when Becky throw the ball over the fence to their neighbor's yard. Evil girl knew that their neighbor, Mrs. Cooper will be furious if she'll catch anyone on her land without her permission. But Belinda didn't know that, so she agreed to return the tennis ball and climbed over the fence without fear.
