Game Changer (Kong Phlik Kem)

synopsis

The city is overrun by competing gangs of mafia. Each of them runs a different kind of racket, and all of them are hungry for money and power. But because of BOSS, they co-exist in a sort of peaceful agreement: Boss collects dirty money from every gang, manages it for everyone's interest, and finds a balance between law and lawlessness. TEE, KID, SIM and TUEK have come from anonymous backgrounds, but they're Boss's closest aides. The game changing point arrives when Boss dies unexpectedly, and the four of them now want to take over his rule. They decide to keep Boss's death a secret and continue to run the rackets as he did. But things prove more difficult than anticipated.
