Synopsis: (Spoiler)

Emil, a boy of 12 years old, lives with his father. Because my father was unemployed and the family life was difficult, my father was reluctant to buy movie tickets to take Emil to the movies on his birthday. But every time his mother sends him 500 marks on his birthday, his father always keeps them for him. Today, the emir has 65,438+0,500 marks.

Emil mentioned his father's unemployment in his composition. The kind teacher told Emil a job opportunity suitable for his father. After an interview, his father finally found a job as a vacuum cleaner agent. However, Emile's father had an accident on the road because of speeding, and his driver's license was revoked. In order to get his father's driver's license, Emil decided to use his own money to get his father's driver's license by staying at his teacher's sister's house in Berlin. On the train, the naive Emil was fascinated by a guy with a pale face and red boots in the same box, and his 1500 mark was missing.

When Emil woke up, the train had not arrived. He looked at the people who got off the bus from the window and finally saw the guy who stole his money. He followed him closely with a box in his hand. In front of a restaurant, he stopped. The bad guy eats with his money, but he is still hungry. Emil secretly took out a piece of bacon from the kitchen, but was caught by the chef's daughter. The chef's daughter is Glacia, about his age. Emil told Glacia what had happened to him. Glacia used his influence to gather a large group of children, who were called "city detectives", each with his own unique skills. Glacia arranged a plan to catch bad guys, code-named "Amy", and put all the children in the necessary positions. At the same time, a special boy disguised as Emil went to the teacher's sister's house to deal with her son Gustav.

Emil and a group of friends have been tracking Glendais, the bad guy who took his 1500 mark, and finally found the box of Glendais from the hotel, but it didn't contain the 1500 mark they expected, but all kinds of precious jewelry and watches that Glendais stole from other rooms in the hotel.

Glacia and Emile met the seller of the driver's license, only to be kidnapped by Grandes. Amir and his partners carefully planned, not only saved Glacia, but also brought the bad guys to justice. Emil's father was also promoted locally, and in his hometown, Emil was reunited with his good partners in Berlin again.
