D-Shroud, a criminal kingpin, has dreams of growing his empire. By selling three suitcase nuclear weapons to buyers that have no compunctions about using them, he believes he can secure his vision. Tease, his number one assassin, is beautiful and deadly. When a mysterious Washington attorney named Shaw asks too many questions about D-Shroud, Tease is ordered to put an end to Shaw's life.
After Tease is abducted by an unknown organization, her face, name, and very identity are eradicated. They train her to be a better assassin. She becomes Sphinx - she's fouled-mouth, hot-tempered, and deadly. Her first mission as Sphinx is to travel to a remote tropical island posing as a scientist to get close to Viceroy, a ruthless drug lord. Her goal is to entice him and to discover all she can about Grandeur, a new, incredibly addictive drug.
