Unwilling to have their investigation hampered by a meddling outsider, the FBI assigns rogue LAPD detective James Carter (Tucker) to the case. Seizing the opportunity as a chance to impress the FBI and ultimately join the Bureau, Carter enthusiastically accepts -- until he discovers that his mission is to "baby-sit" Lee and keep him away from the case at any cost. Carter, who is as arrogant and fast-talking as he is street smart, covertly embarks on a one-man crusade to solve the case. Of course, he must first distract Inspector Lee.
