After rescuing a child prostitute in Cambodia, Tess persuades Jake, Carmen, Nicola and the Team to tackle human trafficking worldwide. Sponsored by the United Nations, she creates a team of what Jake calls Valkyries, six remarkable women that alongside the men of the Team embark on a Herculean effort to rescue victims and pursue traffickers, starting with a degenerate financier that controls a multinational sex enterprise. The team then takes direct action by unleashing their military skills in battles against powerful slavers, Boko Haram in Nigeria and the Mexican cartels. The action turns to combating child trafficking, rescuing captured women abused by the terrorist group ISIS, probing Nigerian prostitution in Europe and Russia, and confronting the appalling sex trade in Mexico, Afghanistan and in the U.S. In a whirlwind series of actions, the story transitions from Phnom Penh to New York, Houston, Miami, Paris, London, Amsterdam, Hamburg, Buenos Aires, and Las Vegas. The deeper the Team gets involved, the more challenging their task becomes. With all cards stacked against them, Tess and Jake must find a way to address the fundamental causes of human trafficking and attempt to formulate a solution to intractable problems.
