The trail of dead bodies begins in Hong Kong and moves to London. Guy Ashton is a dead man walking; no one kills a Chinese Triad Master and lives. His lifeline becomes the CIA, where he is trained to kill by the beautiful but deadly Jinlin. All action moves to Thailand in the quest for the Smiling Pill, a drug so deadly that whole nations will fall under the control of whoever acquires it. The mission: find the drug formula and eliminate the creator. There is a traitor among them who wants the drug for themselves. As the body count continues to mount, Guy is forced into a kill or be killed confrontation with Jinlin. Only one of them will be allowed to live.
