One Saturday afternoon, Kate went to buy something for her sister and herself.
As Kate was coming out of a shop, a young lady walked towards her. She said she was Miss Green, a good friend of Kate's sister's. Kate believed her. Then she called a taxi to send Kate home. She told the driver where he should go. Kate was surprised that it was not in the direction of her home.
"Why?" Kate asked. The lady smiled, but didn't explain the reason.
When they came to a quiet road , a big rude(粗鲁的) man appeared on the road. He stopped the time. Miss Green took out a knife and pointed it at Kate. She asked Kate to keep quiet. The man then started the taxi.
"Oh! I'm being Kidnapped(绑架)," Kate said to herself.
She tried to escape, but she didn't succeed. Suddenly an idea came to her. She took out a lipstick(口红) from her pocket, wrote 'SOS' on the window, and covered the word with her back.
A few minutes later, a police car passed and the policemen saw the sign. When the kidnappers saw the policemen, they stopped the taxi, jumped into the grass, and ran away.
The policemen then picked Kate up and sent her home. When her parents knew what had happened, they were greatly surprised. But they were happy because their daughter had finally come back safely.
