Rookie cop Jake Hoyt wants to stop crooks, not become one. But staying on the right side of the line that separates cop from criminal will be more challenging than anything he's faced. Because Hoyt's senior partner for the next 24 hours is Alonzo Harris, an undercover narc meaner than any of L.A.'s mean streets. In a powerful departure from his frequent good-guy roles, Denzel Washington plays Harris, the twisted but charismatic detective who both attracts and repels as he becomes the kind of thug he's supposed to collar. Ethan Hawke plays unseasoned recruit Hoyt. And Antoine Fuqua (The Replacement Killers, Bait) directs, guiding a cast that includes music stars Dr. Dre, Macy Gray and Snoop Dogg. Training Day. It's a day of reckoning.
