After five years on the run, 'The Gray Man' - Court Gentry - is back on the inside at the CIA. His first mission makes him wish he wasn't, when a pair of Chinese agents try to take him down in Hong Kong. Normally the Chinese stay eyes-only on foreign agents - why are they on such high alert? Court's high-stakes hunt leads to an old friend, Donald Fitzroy, who is being held hostage by the Chinese. Fitzroy was contracted to find Fan Jiang, a former member of an ultra-secret unit responsible for testing China's security systems. But Fan was too good at his job . . . The first two teams Fitzroy sent to find Fan have disappeared and the Chinese have decided to 'supervise' the next operation. What they don't know is that Gentry's mission is to find Fan first and get his intel to the US - and get out alive . . .
