He was looking for a foreign movie he had watched when he was young. The main character was a boy and there were two foreign spy couples. The old woman was missing a few fingers.

This little boy has a friend. He's an adult. It seems that he has some special ability. He might be a shrunken person. I'm not sure about this.
He remembered that the two old spies were bad people. Their goal seemed to be to cheat the boy of a chip. The two of them had a very good relationship with the boy. Later, the couple picked up the boy in the car. The old man drove while the old lady accompanied the boy in the car. At this time, the boy told him what he knew. He said,"I know someone wants to take my chip away. Someone is missing a few fingers. That's all I know." After saying that, the old lady beside him took off her gloves. It turned out that the old lady was the bad guy with a few fingers missing.
At the end of the movie, the little boy's friend seemed to have sacrificed himself to save the boy. I don't remember if he died or not.
Dear movie experts, please help me answer my question ~ It's a childhood memory.

Answer 1

According to the information provided, I guess the movie you want is The Spy Family.

The film was released in 1986 and told the story of a young boy and his two fathers. One of the fathers was a federal agent, the other was a private investigator, and the three of them worked together to help clients escape the police.

In the movie, the plot of the old woman spy who was missing a few fingers appeared in a special mission that required the help of the little boy and his two fathers. After completing the mission, the old woman's finger was cut off, causing her to lose her job.

I hope this movie can satisfy your needs.
