On the Mediterranean island of Mallorca, Roper's life of luxury and calm is shattered.

While he continues to recuperate in Roper's villa, Pine starts to dig up secrets about the other members of the household.

Roper welcomes Pine into his inner circle, leaving Corky out in the cold. Meanwhile, Burr has concerns for the safety of her source.

A suspicious Roper gathers his entourage around him in an attempt to root out the traitor, forcing Pine to play a dangerous game.

Roper and his team return to Cairo for the deal, reuniting Pine with an old enemy. A discredited Burr makes one last stand.
