In the lush world-banking capital of Geneva, Switzerland, three friends from Harvard Business School find their lives and their work unexpectedly intertwined. Catherine and Majid are handling investments for clients with dubious pedigrees. When their friend Rafe shows up in Geneva, he claims to be just another start-up hedge fund manager. But Rafe, after a moral awakening, is now an undercover agent with the U.S. Treasury’s Office of Terrorism and Financial Intelligence and he’s in Geneva secretly investigating his old friends, one of whom was his former lover.

Catherine and Rafe pick up right where they left off, even though she’s now seeing Majid, but she’s soon in a tangle bigger than infidelity when her biggest client appears to be leading her into a trap of money laundering co-conspiracy. And then there’s Majid, who would be more jealous of Rafe if he didn’t have more worrisome problems, such as his biggest client shorting a Nigerian oil company stock right before a catastrophic “accident.” As the CIA closes in on the terrorists themselves, Rafe, with the help of Detective Emmanuel Okoro of the Nigerian police, works to find a way to save his friends and the world at the same time.
