Two Murders. Two Cities. Two Cops from opposite sides of the world ...

… come together to prevent a threat from organised crime to hack a police database taking revenge upon the death of one of their own.

A brutal murder and an abduction, in Hong Kong, leads a Hong Kong murder detective Mandy Lee to the UK. Her investigation finds that a cyber-attack on a police database, puts her in direct conflict with her estranged step brother and an organisation called Crimson Dragon. Joining forces with Northampton cop, PC Ed Roberts, they discover that an incident in London’s Chinatown had occurred two years before, prompting the abduction of the commander of that raid.

Can Lee and Roberts find the abductee and discover the murderers before Crimson Dragon takes its revenge?
