In Too Deep (1999)

Synopsis
In this crime thriller, L.L. Cool J is a underworld boss so powerful that his nickname is "God." He has his fingers in 80% of the drug traffic in Cincinnati, has won over nearly every adversary through bribery or intimidation, and seems practically untouchable. New police detective Jeffrey Cole (Omar Epps), convinced that he's the man who can bring down "God" and his empire, assumes a criminal identity that allows him to infiltrate "God"'s organization. However, the longer Cole remains inside the underworld, the more he finds himself caught up in it, and getting out of "God"'s empire becomes more difficult than getting in. The supporting cast includes Stanley Tucci as Cole's superior, Nia Long as Cole's girlfriend , and Pam Grier as an undercover detective, as well as hip-hop artists Nas and Mya. ~ Mark Deming, All Movie Guide
