Hector Chetwode-Talbot, Eck to his friends, has left the army after a rather nasty moment in Afghanistan. At a loss as to what to do next, he is approached by an old schoolfriend, Bilbo Mountwilliam, who runs an investment fund. He persuades Eck to join the company as a greeter. All Eck has to do is supply his rich contacts with entertainment and large gin and tonics and let the fund managers do the rest.
