For 20 years, Hong Longkun has been a triad boss and regarded as godfather by his men. To ensure security and survival of his operations, he decides to send Yao Deming - whom he also regarded as his godson and adopted after killing the latter's heartless parents - to enrol and infiltrate Singapore Police Force as his eyes and ears.
Guo Shaoqiang was a former gang member and drug runner. Just as his future took a turn for the worse even after release, he was given a chance to redeem himself by his late father's close friend - Inspector Wei by joining Longkun's syndicate and bring it down once and for all.
Soon both the gangster and police informer had to forget everything about who they were and focused on their mission as undercovers for both sides of the law in a thrilling espionage game of cat and mouse.
