Bucum Jackson (ICE CUBE) is a maverick bounty hunter who dreams of opening his own detective agency one day, but until then must put up with his bail bondsman boss, Martinez (ANTHONY GIAIMO), telling him he should take on a partner, a point his coworker, Pam (VALARIE RAE MILLER), thinks is a good idea.
His latest assignment is to find and bring in Reggie Wright (MIKE EPPS), a petty con man who pulls off convenience store shoplifting crime with the aid of senior citizens when not buying lottery tickets for his live-in girlfriend, Gina (EVA MENDES). Reggie and Bucum have a long, cat and mouse history together, and the pursuit and fleeing begins once again.
This time, however, Reggie ends up in the back of a van, hidden from the view of criminals Ursula (CARMEN CHAPLIN) and Ramose (ROGER GUENVEUR SMITH) who've just killed several people to steal millions of dollars worth of diamonds. The only problem is, the diamonds turn out to be fakes and the two know that their boss, Robert Williamson (TOMMY FLANAGAN), will be none too happy about that.
When they discover Reggie in the van, he acts like he knows where the real diamonds so that he can escape, but unknowingly leaves his wallet behind. Since Ursula opened fire on Bucum during their departure from the crime scene, he's now interested in catching them as a means to some free publicity for himself.
Meanwhile, upon learning that he had the winning lottery ticket in his wallet, Reggie wants to find them so that he can retrieve it. From that point on, the two men then reluctantly agree to become partners of sorts so that they can succeed in their respective quests.
