Please answer the following question: The following article contains an answer for the question: Who does Frank transport a briefcase for? , can you please find it? Frank Martin is a highly skilled driver known as "The Transporter." He will transport anything, no questions asked, always on time, and is the best in the business. He strictly follows three rules when transporting: Don't change the deal, No names, and Never open the package. In Nice, Frank is hired to transport three bank robbers with his black BMW 735i, but they hoist a fourth man in his car after the robbery. Explaining the extra weight will affect his precisely planned getaway, he refuses to drive until, in desperation, the leader kills one of his men who is pushed out of the car. Later they offer more money for Frank to drive them to Avignon. He refuses the deal. The robbers escape in another car but are foiled by their amateur driving. At Frank's villa on the Mediterranean, local Police Inspector Tarconi questions Frank about the black BMW that fled the scene of the robbery. However, with no real proof, Tarconi leaves. Frank is then hired to deliver a package of 50 kilograms (110 lb) to an American, Darren "Wall Street" Bettencourt, that is loaded into Frank's trunk. While changing a flat tire, Frank notices the package moving. Realizing a person is inside, he violates Rule No. 3 in order to give the person something to drink. He discovers a woman, who is tied up and also gagged with tape on her mouth (Shu Qi). She attempts to escape but Frank recaptures her and returns her to the trunk along with two policemen who spot them. Frank delivers the package to Bettencourt as promised and agrees to transport a briefcase for him. Frank stops to buy sodas for the cops in his trunk, but they are killed by the bomb hidden in the briefcase. Out for vengeance, Frank returns to Bettencourt's villa, where he kills and wounds several of Bettencourt's henchmen. Frank then steals a car to get away, only to find "the package" bound and tapegagged in the back seat. He brings the young woman, who is named Lai, back to his house.
