Powerful businesswoman Nessa Stein is embroiled in a dangerous political game when a Palestinian businessman with close connections to her family's empire is killed.

Nessa's past, including her kidnapping in Gaza eight years ago, is unearthed by MI6 boss Sir Hugh Hayden-Hoyle, who is intent on getting answers despite being blocked by the CIA.

Nessa's security adviser follows a lead in the hunt for a missing boy, while her brother Ephra makes a startling discovery that could blow the family, and its work, apart.

Eight years ago, a younger Hayden-Hoyle climbs the ranks of MI6 as Nessa and Atika endure atrocities while being held captive in Gaza and their captors scheme for ransom.

As their captivity continues, Atika and Nessa share a secret that will bond them together forever. Meanwhile, an academic in Tel Aviv, working at a university funded by the Steins, uncovers corruption that could have far reaching consequences.

When a Palestinian businessman makes Nessa an offer regarding the cabling initiative in the Middle East, Nessa learns the full cost of her release from captivity eight years ago.
