A very skilled pick-pocket gang of four teenagers, consisting of two boys and two girls, always works like a team and never gets caught. This time they use their expertise to steal the “Sedan”, a ten million baht worth diamond, from an Arab gang while they are making a deal with a dishonest businessman. Police officers Chanat and Daecha are assigned by their superior to handle this case. After an intensive investigation, they suspect the pick–pocket gang, but there’s not enough evidence to make an arrest. Once the Arab gang is out to hunt down the four teenagers, the police have to come in to save them and fight with both the Arab and the not-so-honest businessman gangs.
