Mike is between ventures and getting antsy when he's offered an intriguing proposition: start up a new company funded by billionaire tech icon Barry Samson. But when Samson is found murdered, and Gold's friends start disappearing, the FBI targets him as a suspect. To protect his family, his reputation, and his freedom, Mike has to unravel a puzzle involving his best friends, buried events from his childhood, mysterious women, and retired mobsters. And he better move fast, because the FBI is after him and time is running out.
