A quartet of kidnappers make the mistake of hiring Da Silva as their driver
Chico Xavier needs cash. His father has cut off his allowance, and for a student with expensive taste this is a death sentence. He and his friends arrange to kidnap one of their school friends who allows himself to be taken in exchange for a cut of the ransom. Two days of criminal behavior and they'll all live happily ever after – or Chico thinks.
To store the victim of their faked kidnapping, Chico's girlfriend pays a taxi driver for the use of his house. But the driver is no ordinary cabbie – he is Captain José Da Silva of Interpol. He can't tell if Chico's scheme will turn out to be tragedy or farce, and so he plays along, hoping to save the kidnappers from themselves.
