The incredible Grace Flint is back. She is the best undercover cop in the business, a chameleon personality who can assume many different personas. She is a driven woman, tortured by past betrayals and now she has a burning desire to avenge her tormentors. Karl Grober is a vicious East European money-launderer, one of the FBI's Ten Most Wanted criminals. Flint is assigned the task of infiltrating his organisation and bringing him to justice, dead or alive. She is going deep undercover. She joins a financial investment company as a tax expert and attempts to pull off an outrageous sting; she sows the seeds of doubt in Grober's ally -- Alexander Carcani, an Albanian running a prostitution and child body-farming ring. But Flint has a young son - the chink in her armour - and when she realises somebody knows everything about her and is determined to target her weakest point, it's inevitable that all hell will break loose!
