Hotel night manager Jonathan Pine receives a plea for help from a well-connected guest. His actions draw him into the world of Richard Roper, businessman and arms dealer.

A glamorous party held by Roper's business associate Juan, in honour of his daughter's birthday, soon turns sour when the guest of honour is found dead. Roper digs deeper into Pine's past and confronts him over what he's found already, he then offers him a position in his operation, but Corky remains deeply suspicious. Pine takes Daniel into town, giving him an opportunity to share information about Roper's operation with Burr. Burr uses Apostol's guilt to her own advantage and tells Roper and Langbourne that Corky is the leak.
