Introduction:

After screwing up a major drug bust in New York, two African-American FBI agents (who are also brothers) , Marcus (played by Marlon Wayans) and Kevin (played by Shawn Wayans), try to atone for their mistakes so that their bosses will change their minds. So they volunteered to protect the Wilton sisters, Tiffany (Anne Dudek) and Brittany (Maitland Ward), from New York's JFK Airport to the Hampton Inn. The journey was safe and sound. The Wilton sisters have hundreds of millions of assets, but they are also being coveted by criminals, who are always looking for the right time to kidnap them in order to obtain a large ransom.

After deciding to change their current situation to offense instead of defense, the two brothers decided to use themselves as bait to lure criminals into taking the bait. So they hired FBI makeup experts to apply a thick layer of white powder on their faces, and matched them with the Wilton sisters' costumes. In a blink of an eye, they became the real "Wilton sisters". They hid and protected the real Wilton sisters, and then all they had to do was make the world believe that they were the real young, wealthy and fair-skinned heirs to the sisters' legacy, including hiding the colleagues and threats who now protect "them".
