Sammo and Tyrell accidentally mess up an Interpol undercover operation when they arrest some arms dealers. Charlton McCallister, the Interpol agent, knows that the female arms dealer he was pretending to work for has a very big deal coming up. Amy volunteers to go undercover, even though she has no experience of that kind of work. At her first meeting McCallister gets shot and injured and she has to carry on without him. Sammo takes on the part of her butler/bodyguard so that they can try and find out exactly what is being sold and who is out to buy it.
