In the exotic city of Singapore, Paul Rimmer's first meeting with Lin Tan, his counterpart in the Singapore Bureau, bodes ill for the joint mission to bring down John Chan, the head of a new drug cartel.

Assigned to lead a joint operation with Lin, Paul questions the inclusion of this tiny and attractive operative. This is his opportunity to redeem his previous failure in bringing Chan down, and he will not let his operation be hindered by a rookie.

Lin's oath of justice is fed by revenge. Her sister was murdered by John Chan and her pursuit of Chan is deadly. Although attraction flares between them, Paul suspects Lin may be a double agent working for Chan.

As Paul and Lin assemble an unusual team and zero in on the drug lord, will they succeed in the mission, or will revenge bring them down?
