You're a man with no friends left in the world thinking about doing yourself and your enemies a favor and ending your life. Moments before you can carry out your plan, however, you see a young girl in need of your help. Do you go to her aid? If your answer is no, you just shortened this movie by about 98%.
When we first meet Luke Wright (played by Jason Statham), he's won a mixed martial arts bout that the Russian mob "encouraged" him to lose. An easy enough task given the fact that he already had a losing record. After they assault him, he believes the worst is behind him. That proves to be false when he returns home to find members of the same Russian mob have killed his girlfriend (or wife, I'm not entirely sure and the information sources I've checked are silent on the matter). Rather than kill him, he's left as the prime suspect in the homicide and told to leave the mob's territory. On the other side of the world, a ten year-old Chinese student named Mei (played by Catherine Chan in her first feature film) demonstrates an exceptional gift for remembering numbers regardless of length or complexity. When the nature of her gift becomes common knowledge in her hometown, she becomes the ward of a local businessman with consent of her father whose hands are full thanks to her mother's serious illness. The businessman is a member of the Triads, Chinese organized crime for those who are unfamiliar, and intends to use her gift in America in lieu of written or computer files, as both can be seized by law enforcement. In time, they trust her unflinchingly and ask her to remember a very long number and relay it to the Russians who will give her another number to bring back. But when her escorts are shot en route to the Russians, she runs and they chase her. She makes it to the subway where a despondent Luke (Statham) subdues her pursuers and makes himself the one man in New York who the Triads, the Russians, and the NYPD officers on their payroll all want dead.
Now, I like Jason Statham. While I don't own copies of any film in either the Transporter series or the Crank series, I do own DVDs of The Mechanic and Death Race despite the fact that both films received generally negative reviews from the majority of critics. However that might reflect on my credibility, I thought that this was a very entertaining action film.
