The local
police inspector, Alistair Martland—who is desperately in love with Johanna—enlists Charlie to help recover the artwork, not least because Charlie has underworld connections and deep expertise in art forgery.Spurred by the promise of a hefty reward that would solve all his money troubles, Charlie embarks on a chaotic
international manhunt accompanied by his fiercely loyal, hyper-masculine, and sexually insatiable valet, Jock Strapp. Their investigation immediately attracts the wrong kind of attention.

She uses her own romantic leverage over Martland to manipulate the police force into protecting them.The climax unfolds at a lavish Los Angeles auction hosted by an eccentric billionaire terrorist who is secretly purchasing the stolen Goya. Charlie devises an elaborate, high-stakes con to switch the real painting with a clever forgery he commissioned. Through a mixture of sheer dumb luck, Jock’s lethal combat skills, and Charlie’s surprisingly sharp eye for deception, the plan succeeds. The criminals turn on one another in a chaotic shootout, allowing Charlie and Jock to escape with the authentic masterpiece.Returning triumphant to England, Charlie hands the Goya over to the authorities, securing not only the substantial reward money needed to clear his crushing tax debt but also a hidden compartment within the frame containing millions in smuggled Nazi gold. With their financial future secure and their adventurous marriage reignited by the thrilling chaos, Charlie and Johanna celebrate their victory, proving that beneath his ridiculous facade and aristocratic eccentricities lies a surprisingly cunning survivor.
